(Lythrypnus dalli) Moderate Peaceful 2" 10 gallons 60-70° F, dKH 8-12, pH 8.1-8.4, sg 1.020-1.025 Carnivore Eastern Pacific, California, Mexico Gobiidae Gobies Reef Compatible The Catalina Goby (Lythrypnus dalli) is without a doubt a very attractive and exotic looking species. Their bright orange-red body and electric blue vertical stripes makes them truly glow under the bright aquarium lighting. However, unlike most brightly colored tropical reef species, the Catalina Goby is a cold water species that requires aquarium temperatures much lower than that of typical coral reef fish species. While most fish species commonly found in the aquarium hobby require water temperatures in the 76° to 82° range, the Catalina Goby requires much lower temperatures in the 58° to 70° range. Due to their specific water temperature requirements and small adult size of only 2 inches, the Catalina Goby is most often housed in nano aquariums designed to replicate their natural cold water habitat. Catalina Goby are found living in shallow rocky coastal waters ranging from California in the north to the Gulf of California off the Mexican coast. They are most often found in rocky coastal areas, where they utilize the fields of boulders for both protection and for hunting grounds. Catalina Goby work their way through the rocky caves and crevices looking for small crustaceans and other similarly sized marine organisms on which to prey. They also utilize the rocky caves and tight crevices in order to hide from other larger fish species that would see them as a food item. They require an aquarium environment that will provide them with the highly oxygenated and cool water conditions of their native territory, along with plenty of rocky caves and crevices to explore. While territorial towards its own kind, Catalina Gobies will co-exist with most other fish species including other small similarly sized and shaped species. They can even be kept in small groups of their own kind in aquarium large enough to provide ample territory for specimen, generally an aquarium 40 gallons or more. Single specimens can do well in both nano and pico aquariums, ranging from 5 to 30 gallons in size. Tank mates should include other cold water fish species that are not large enough to see the Catalina Goby as food. Catalina Goby coexist well with both temperate water corals and invertebrates, like Anemones, Feather Dusters and shrimp. While the Catalina Goby can tolerate warmer water temperatures upwards of 74° for short periods of time, they will not thrive in these conditions and will be much more susceptible to disease and an overall shorter lifespan. Their ability to change their sex is one of the more interesting aspects of the Catalina Gobys reproductive behavior. While each Catalina Goby has the reproductive tissues of both genders, they can only display one sexual orientation at any given time. If a Catalina Goby finds itself unsuccessful as one gender, it can switch to the other. Behavioral males are generally larger and have a longer dorsal fin with black tips on the longest dorsal fin rays. When they are ready to breed, a behavioral male chooses a cave in which to care for his brood. He then lures the female inside, where she will attach her eggs to the walls of the cave. He will care for the eggs there until they hatch. The Catalina Goby is a typical Goby in regards to feeding, eating all types of small crustaceans, plankton and small invertebrate species like amphipods and copepods. They are very hardy eaters that will quickly adapt to both aquarium life and commercial fish foods. They do best with meaty preparations like brine shrimp, mysis shrimp, flake and vitamin-enriched frozen foods designed for marine carnivores.

(Gobiodon histrio) Easy Peaceful 2" 30 gallons 72-80° F, dKH 8-12, pH 8.1-8.4, sg 1.020-1.025 Carnivore Indo-Pacific Gobiidae Gobies Reef Compatible Green Clown Gobies are a very small, brightly colored species that have a comical appearance and great personalities. They are generally found among Acropora corals throughout the the reefs of the tropical Indo-Pacific region. Green Clown Gobies are immensely popular as "nano" and even "pico" (although at least 30 gallons is recommended) fish species and are quite often utilized in larger reef systems where they will always bring that extra little bit of comedy and personality. Green Clown Gobies and all their Gobiodon relatives have the ability to secrete a toxic mucus, forming a defensive layer on the skin; heterospecific predators will usually leave them alone knowing that they are "off limits". The Green Clown Goby is a cute and peaceful fish that is an excellent choice for beginners who are learning the ropes as they are easy to care for and are quite hardy once established in their aquarium. The Green Clown Goby is readily available throughout the hobby and can be purchased through local stores as well as online retailers. The Green Clown Goby must be housed in an aquarium of at least 30 gallons and should be provided with a live sand substrate and plenty of live rock for grazing, perching and refuge. They greatly appreciate the presence of established Acropora colonies as they will commonly feed from them and use their dense branches for shelter. Due to their tiny size, Green Clown Gobies have a very minimal impact on the biological load of their aquarium and don't require any special filtration needs other than a quality biological and mechanical setup. Although they are generally a peaceful species, they can become territorial and aggressive with conspecifics; multiple Green Clown Gobies in the same aquarium require ample space, separate territories, and must be introduced simultaneously. They tend to coexist happily with other peaceful tank mates, but their eating habits should be closely monitored if housed with aggressive feeders (to ensure they are getting enough to eat); once acclimated and well established they will be able to coexist well with aggressive feeding tank mates. They are a reef safe species, but have been known to nip at Acropora corals and should only be housed with well established colonies that will be relatively unaffected by their small presence (even though they share a mutually beneficial, symbiotic relationship). Green Clown Gobies are carnivores that mainly eat amphipods, copepods as well as other zooplankton and benthic invertebrates among the reefs of their natural habitat. A supply of live amphipods or copepods would be appreciated in addition to a variety of live, frozen, freeze-dried, and vitamin-enriched brine shrimp, mysis shrimp, cyclops, bloodworms, and chopped seafood. They may also accept quality pellet (soft) and flake foods for carnivores and omnivores. Green Clown Gobies should be fed once or twice a day, only what will be consumed in a few minutes.

Citrinus Clown Gobies are an extremely popular choice for "nano" aquariums as well as peaceful reef tanks and they pack a lot of personality into a very small package. The Citrinus Clown Goby is sometimes referred to as the Poison Goby due to its ability to secrete a toxic mucus, forming a layer on its skin; heterospecific predators usually know not to mess with them and will generally leave them alone. The Citrinus Clown Goby is a peaceful fish, but can sometimes become territorial with conspecifics and multiple specimens should have adequate territory and be introduced to the aquarium at the same time. The Citrinus Clown Goby will get along well with other peaceful tank mates, but should be watched if housed with aggressive feeders. Citrinus Clown Gobies are easy to care for (once established) and are a wonderful species for beginners as well as more experienced hobbyists alike; due to their growing popularity they are readily available throughout the hobby and are offered at very reasonable prices. The Citrinus Clown Goby must be housed in an aquarium of at least 30 gallons and should be provided with a sand substrate and plenty of live rock for grazing, hiding, and perching. They really appreciate the presence of established Acropora colonies as they will commonly feed from them and use their dense branches for shelter. Due to their tiny size, Citrinus Clown Gobies have a very minimal impact on the biological load of their aquarium and don't require any special filtration needs other than a quality biological and mechanical system. As a peaceful species that predators recognize as "off limits", they can coexist well with many other inhabitants, but conspecifics should be added to an aquarium at the same as they can sometimes become territorial with their own. They are a reef safe species, but have been known to nip at Acropora corals and should only be housed with well established colonies that will be relatively unaffected by their small presence (even though they share a mutually beneficial, symbiotic relationship).

(Eviota pellucida) Easy Peaceful 1" 12 gallons 72-80° F, dKH 8-12, pH 8.1-8.4, sg 1.020-1.025 Carnivore Philippines Gobiidae Gobies Reef Compatible The Gold Neon Pygmy Goby, sometimes referred to as the Neon Eviota Goby, is endemic to the Philippines and considered to be rare within the hobby. The Gold Neon Pygmy Goby is an excellent choice for a "nano" aquarium as they are a tiny species and will provide bright red and gold color with a very small biological impact on their habitat. Gold Neon Pygmy Gobies are highly active and also love to perch on coral and live rock while making sure they aren't missing anything as they keep an eye out for amphipod and copepod snacks. Gold Neon Pygmy Gobies are both beautiful and popular, but can be hard to find within the hobby. The Gold Neon Pygmy Goby should be housed in an aquarium of at least 12 gallons and be provided with a fine sand substrate and plenty of live rock for grazing, hiding, and perching. Because of their tiny size, they have a relatively small impact on their environment and don't require any special filtration needs above a quality biological and mechanical system. They are a very peaceful species and should be kept with peaceful tank mates of a similar size as they can be picked on or eaten by larger, more aggressive fish as well as invertebrates. Gold Neon Pygmy Gobies are carnivores and mainly eat amphipods, copepods, and other planktonic food among the corals and reefs within their natural habitat in the wild. A supply of live amphipods or copepods would be ideal in their aquarium, but they will accept other meaty foods such as live, frozen, freeze-dried, and vitamin enriched brine shrimp, finely chopped mysis shrimp, cyclops, and other finely chopped or prepared seafood as well as tiny pellets and flakes for carnivores and omnivores. Gold Neon Pygmy Gobies should be fed twice a day.

(Amblygobius rainfordi) Moderate Peaceful 3" 20 gallons 74-80° F, dKH 8-12, pH 8.1-8.4, sg 1.020-1.025 Omnivore Western Pacific Gobiidae Gobies Reef Compatible Rainford's Goby, sometimes referred to as the Court Jester Goby, is native to the Western Pacific reefs and packs a lot of color in a small package; Rainford's Goby is extremely popular for "nano" aquariums due to its vivid coloration as well as its very small size and environmental impact. This species tends to stay near the bottom of the aquarium constantly sifting around for copepods and nibbling on filamentous algae. Rainford's Goby is a beautiful species with a greenish-tan base color that shifts to a greenish-yellow around the head; it has several solid white spots on each side at the base of its dorsal fin in addition to multiple, bright orange horizontal lines running from its face, across its eyes, all the way to its caudal fin; it also has a black ocellus spot on the rear section of its dorsal fin and a less noticeable one on the top base of the caudal fin. Rainford's Goby is quite popular in the hobby and can be found through local and online vendors alike. Rainford's Goby should be housed in an aquarium of at least 20 gallons and be provided with a fine sand substrate and plenty of live rock for grazing and hiding; the species spends a lot of time sifting around on the bottom and among the rocks in search of food. Rainford's Gobies have a very small impact upon their environment which is helpful in regards to the biological load of the system and provides additional tolerance for other fish or coral species to be added to a reef aquarium. They are a very peaceful species and should be kept with peaceful tank mates of a similar size as they can be picked on by larger, slightly more aggressive fish. Rainford's Goby is an omnivore and in addition to eating filamentous algae, it can be found sifting around in the sand for copepods and other planktonic snacks within their natural environment. A supply of live copepods would be ideal in the aquarium, but other meaty foods such as live, frozen, freeze-dried, and vitamin enriched brine shrimp, and finely chopped mysis shrimp; Spirulina-based omnivore pellets and flake foods should also be used. This species likes to graze and should be fed 2 to 3 times per day.

(Gobiodon okinawae) Easy Peaceful 1" 12 gallons 72-78° F, dKH 8-12, pH 8.1-8.4, sg 1.020-1.025 Carnivore Indo-Pacific Gobiidae Gobies Reef Compatible Yellow Clown Gobies hail from tropical reefs and quiet lagoons spread throughout the Indo-Pacific, where they can be found living amongst the branches of corals and rocky outcrops. They are typically found in small groups of 5 to 20 individuals where they tend to stay close to the protection of hard corals or rocky crevices and caves. It is amongst the coral branches that Yellow Clown Gobies look for small plankton in the currents on which to feed, all the while keeping an eye out for larger predatory fish species. Yellow Clown Gobies make a great addition to peaceful community aquariums and nano reef aquariums where they can coexist with other peaceful species. Yellow Clown Gobies bring an intense splash of yellow color to any tank they inhabit, but are also known for their entertaining demeanor and interesting swimming style A small peaceful species, the Yellow Clown Goby makes a great addition to any reef or nano reef aquarium containing other peaceful fish species and corals. Yellow Clown Gobies appreciate the presence of plenty of live rock or branching type corals that it can swim near or perch on. Yellow Clown Gobies are a very easy going species that coexists well with other fish species and rarely if every show aggression to fish, invertebrate or corals. They are a shy species that will need to be able to stake out some territory amongst the coral branches of live rock outcrops in order to feel secure and at home. They also prefer a place within the aquarium that they can swim with moderate currents that allow them to stay near their live rock or coral home and still have small meaty food items passing by in the current. Yellow Clown Gobies are easily bullied by larger more aggressive fish species, so their tank mates should be chosen with care. If possible, the Yellow Clown Goby should be added to the aquarium before more boisterous community fish species so that they have time to adjust to their new home and stake out their territory. In the wild the Yellow Clown Goby is an opportunistic feeder that waits patiently for small species of plankton to float near their home territory, then they will dart out to consume it. Once they are established within their aquarium environment and more at home, they will readily feed on a variety of small meaty food items. Suitable meaty items include: Cyclop-Eeze, brine shrimp, mysis shrimp, meaty flake and frozen foods, copepods and other small meaty marine organisms.

(Elacatinus multifasciatus) Easy Peaceful 2" 10 gallons 72-78° F, dKH 8-12, pH 8.1-8.4, sg 1.020-1.025 Carnivore Caribbean, Puerto Rico Gobiidae Gobies Reef Compatible The Greenbanded Goby makes an excellent "Nano Fish" as it does very well in smaller aquariums that contain other peaceful reef species. They will spend much of their time scooting from rock to rock all around the aquarium, while looking for small meaty prey living in caves and crevices within the live rock. There coloration can be described by nothing less than vibrant, as they have vivid green with thin iridescent green bands running vertically down the body along with a white head with a brownish red band runs across each red eye. Greenbanded Gobies do so well within the marine aquarium environment that they are even known to frequently spawn in a proper setup. Greenbanded Gobies are a very peaceful fish species that is best kept with other very peaceful species. It is recommended that if kept with other Goby specimens, that the Greenbanded Goby be added first so that it can establish territory before other more aggressive Gobies are added to the aquarium. The Greenbanded Goby should be housed in a 10 gallon or larger aquarium containing a sandy substrate and plenty of live rock. This species will spend much of its time hovering around the live rock and similar decor. Greenbanded Gobies can be kept in small groups of 3 or more or as mated pairs. It is best not to keep this species with other more aggressive species like Hawkfish, sand perches or aggressive Dottybacks that will compete to aggressively with the Greenbanded for territory and food. Greenbanded Gobies should be fed a varied diet consisting of live and frozen brine shrimp, frozen mysis shrimp, chopped fresh seafoods, and frozen food preparations for carnivores. They should be fed twice a day as much as they will consume within a few minutes.

(Amblyeleotris wheeleri) Easy Peaceful 3" 10 gallons 72-78° F, dKH 8-12, pH 8.1-8.4, sg 1.020-1.025 Carnivore Indo-Pacific Gobiidae Gobies Reef Compatible Wheeler's Watchman Gobies are well known for their attractive appearance and suitability for smaller aquariums. Wheeler's Watchman Gobies are considered a good "Nano" fish as they only reach a max size of about 3 inches and spend the majority of their time near their burrow awaiting an opportunity for a meaty meal. This species will quickly adapt to life within a Nano Reef Aquarium or smaller Reef Aquarium where they will dig out a burrow, in which they will live in and near. They require a mixed substrate of sand and crushed bits of coral that they can comfortably dig in and that will support the construction of 2 to 3 inch deep burrow. In the wild Wheeler's Watchman Gobies get the "Watchman" portion of their name from the fact that they will often share burrows with Alpheus Shrimp, with whom they have a symbiotic relationship. Alpheus Shrimps who are almost completely blind, will dig out very extensive burrows that they will then share with Watchman Gobies in return for the Gobies ability to see trouble coming and alert the Shrimp to retreat into the burrow. This species is known for adapting to the home aquarium very quickly and living and thriving in small aquariums of 10 to 25 gallons in size. It is for this reason that the Wheeler's Watchman Goby is considered an excellent species for keeping in the very popular Nano aquariums that are becoming more and more commonplace. Wheeler's Gobies are also known for being very disease tolerant and hardy with little no special housing requirements beyond a sandy substrate and some live rock present to create their burrow near. They will also do well in small groups or pairs as long as they are all added at the same time, so that they can establish their own territories within the aquarium. Overall the Wheeler's Watchman Goby is an excellent addition for a Nano reef aquarium or community aquarium containing other peaceful fish species. Their diet should include a variety of live and frozen meaty foods such as, brine shrimp, mysis shrimp, live black worms, finely chopped seafood, and prepared foods for carnivores. Wheeler's Gobies should be fed twice daily an offering of varied meaty selections. A varied diet of these meaty marine foodstuffs will ensure that the Wheeler's Goby gets a balanced nutritional diet and will help them maintain a strong immune system.
