(Ophioblennius steindachneri) Moderate Semi-aggressive 5" 50 gallons 72-80° F, dKH 8-12, pH 8.1-8.4, sg 1.020-1.025 Herbivore Eastern Pacific, Gulf of California, Peru Blenniidae Blennies Reef Compatible The Large-banded Blenny (Ophioblennius steindachneri) is found inhabiting rocky shallows from the Gulf of California to northern Peru. Large-banded Blennies live in small holes or crevices near rocky shallow slopes just off the beach, where they spend much of their time darting out of their rocky home to feed on algae and plant matter and then darting back into their protected rocky crevice. They will aggressively defend their home from other small fish, invertebrates or crustaceans that attempt to enter their rocky home or the immediate territory. Aquarium hobbyists should consider their natural lifestyle and provide them with plenty of small rocky caves and crevices to allow them to select a home and territory that suits them. Large-banded Blennies are well suited for both reef aquariums and FOWLR setups. They should be provided an aquarium setup that has both a sandy or mixed sand/crushed coral substrate and plenty of live rock. Live rock is important as it will enable the Large-banded Blenny to establish a home cave or crevice and a surrounding territory. They will protect their territory against other Blennies or similarly sized and shaped fish species like Dartfish, Basslets, Chromis, etc. Thus it is important to house them in an aquarium that allows for multiple territories if they are to be kept with other Blennies or similar species. While they can kept successfully in nano style aquariums, they are better suited for mid sized or larger aquariums ranging from 50 to 90 gallons or larger. Large-banded Blennies do well with most other community fish species, corals and invertebrate species if given ample room to establish their own home territory. Large-banded Blennies are reef safe and are considered a beneficial species to keep in a reef aquarium as they will actively consume a variety of marine algae, which helps to keep the reef clean and clear of excess or nuisance algae growth. In the wild the Large-banded Blenny grazes on marine algae, using its comb-like incisor teeth to scrape algae off of rocks and sessile invertebrates. In the aquarium they will graze on existing marine algae, but should be offered a variety of fresh and prepared marine algae, vegetable matter, and Spirulina-based flake and pellets foods (treated with Selcon for additional benefits) as well as other prepared foods. Feed two to three times per day an amount of food that they will consume within a few minutes.

Triple Spot Blennies have bushy cirri (whisker-like appendages) protruding from between the eyes and are also equipped with combed teeth for eating algae. Triple Spot Blennies have intricate markings that range from white to a tan, brown, and bright red coloration. Triple Spot Blennies are easy to care for, but prefer to have an established system with stable water conditions. As a peaceful species, they will get along well with many other tank mates (generally minding their own business), but they don't play well with other blennies or species with a similar appearance. Due to the comical, inquisitive personalities, and their attractive, contrasting color form, Triple Spot Blennies are becoming increasingly more popular within the hobby. They are fairly easy to acquire and can usually be purchased through local and online retailers. Triple Spot Blennies should be kept in an aquarium of no less than 30 gallons and provided with a sand substrate in addition to plenty of live rock for grazing, perching, and refuge. As many species of blennies have been known to jump when startled, their aquarium should be provided with a secure hood to prevent injury. They do prefer stable water conditions and a decent amount of circulation, so they should be provided with quality biological and mechanical filtration; a protein skimmer is also a welcome addition and will help keep their system clean. They are a peaceful species that will generally keep to themselves, although they love to find a nice spot to perch and watch what's going on in the aquarium. They will coexist with many different heterospecific tank mates as long as they do not have a similar appearance or are an overly aggressive species they may harass them. They should not be housed conspecifically unless as a mated pair. Triple Spot Blennies are great for "nano" aquariums and reef systems, although some blennies are known to occasionally nip at coral polyps and clam mantles. Triple Spot Blennies are herbivores that are built for and prefer eating marine algae in their natural habitat. In an aquarium environment they will naturally graze on existing marine algae (which they generally prefer), but should also be offered a variety of live and prepared marine algae, vegetable matter, and Spirulina-based flake and pellets foods (treated with Selcon for additional benefits) as well as other prepared foods for omnivores and herbivores. Feed twice per day, but only what they will consume in a few minutes.

Ember Blennies can be found among the tropical reefs throughout the Indo-Pacific, from the eastern coast of Africa, all the way out to Fiji and Hawaii. Males of the species are generally larger than females. Ember Blennies have a pair of bushy cirri (whisker-like appendages) protruding from between the eyes and are equipped with adapted, combed teeth to help with their algae grazing tendencies. Ember Blennies have a wonderful personality and are quite peaceful when kept with similar mannered tank mates. Although they are not aggressive, Ember Blennies should be housed individually as they do not prefer the company of conspecifics (unless paired or introduced at the same time as juveniles) or having to share their aquarium with fish of a similar appearance. The Ember Blenny is an entertaining species to observe within their aquarium as they always like to find and settle on a comfortable perch while watching their environment to see what's going on; they can also be observed grazing among the live rock and substrate for algae and planktonic snacks. Ember Blennies are becoming increasingly more popular within the hobby; they are generally available through online vendors and can usually be special ordered from local retailers if not already on hand in the store. The Ember Blenny requires a well established aquarium of at least 30 gallons and should be provided with a sand substrate as well as plenty of live rock for grazing, hiding, and perching. Many Blenny species are known to be jumpers and as a precaution their aquarium should be equipped with a hood or sealed top to prevent escape or injury. As a larger species of Blenny, if they are housed in an aquarium of the minimum recommended volume, the Ember Blenny should be provided with a protein skimmer in addition to quality biological and mechanical filtration (they prefer stable water conditions as well as adequate water movement). They are an inquisitive and peaceful species that will coexist well with a number of different tank mates, but they should not be kept with overly aggressive or territorial fish that will harass them into constant hiding. The Ember Blenny is an ideal species for a reef aquarium and they will assist with removing unwanted nuisance algae growth.

(Meiacanthus oualanensis) Moderate Semi-aggressive 5" 30 gallons 72-80° F, dKH 8-12, pH 8.1-8.4, sg 1.020-1.025 Omnivore Indo-Pacific, West Pacific Ocean Blenniidae Blennies Reef Compatible The Canary Blenny is vividly colorful, bright yellow to orange-yellow species (with a slight green hue on their head) that is endemic to the tropical reefs throughout the Indo-Pacific and West Pacific Ocean. Canary Blennies (also known as the Canary Fang Blenny) are one of the few blenny species (Meiacanthus) that possess enlarged fangs with associated venom sacs which are primarily used as a retaliatory defense and serve as a deterrent to predators; their bite is not lethal to humans but it is extremely painful (similar to a bee or wasp sting); hand feeding is strongly discouraged. Canary Blennies have long, slender bodies with an elegant, forked tail and can usually be observed swimming around the middle to upper levels of the aquarium, playing in the current or looking for planktonic food within the water column and among live rock. Canary Blennies are generally peaceful with other species, but do not normally tolerate conspecifics, unless living as a mated pair; they will coexist well with many heterospecific tank mates and will not be bullied by larger or more aggressive fish species due to the presence of their fangs (fish that attack them will soon learn to pick on someone their own size). Canary Blennies are an ideal choice for the reef aquarium as well as "nano" systems (provided they have plenty of swimming space) and are a great choice for beginners as well as advanced hobbyists. Canary Blennies were once quite rare in the hobby, but have become very popular as a result of their appearance, boldness, personalities, and reef compatibility; they are readily available within the hobby and can be purchased from online vendors and local retailers alike. Canary Blennies should be housed in an aquarium of at least 30 gallons with plenty of open, unobstructed swimming space, a sand substrate, and plenty of live rock for hiding and hunting. They can sometimes jump if startled and should be housed in an aquarium with a sealed enclosure or a tight fitting hood to prevent escape or injury. They should be provided with a good amount of water movement as well as quality biological and mechanical filtration (a protein skimmer is also a great idea to ensure water quality). Canary Blennies are relatively peaceful and can defend themselves if bothered by other fish species; aside from not getting along with conspecifics, they can coexist well with many other tank mates and are completely reef compatible (they will not harm coral species, sessile invertebrates, or ornamental crustaceans). They tend to mind their own business and will provide beautiful coloration and constant activity to any aquarium. Canary Blennies are omnivores that mainly feed on plankton within their natural habitat. In the aquarium they should be supplied with a variety of live, frozen, freeze-dried, and vitamin-enriched amphipods, copepods, cyclops, brine shrimp, mysis shrimp, finely chopped krill, and other prepared marine food items. They should also be offered quality flake and pellet foods (carnivore, omnivore, and herbivore) as well as other prepared food items. Feed once or twice a day.

Both nicknames are direct results of physical characteristics, such as being equipped with combed teeth, which assist with eating marine algae, as well as the presence of a bright yellow-orange caudal "tail". Black Combtooth Blennies also have bushy cirri (whisker-like appendages) protruding from between the eyes, which help them blend in to their surroundings as they forage for marine algae throughout the coral reefs of the Pacific Ocean. Black Combtooth Blennies like to perch on (or in) corals and live rock and watch the aquarium; they also like to burrow into the substrate and hide among various caves and crevices. Black Combtooth Blennies are peaceful and can make excellent additions to "nano" reefs and larger reef systems alike. Black Combtooth Blennies prefer the stable water conditions of a well established aquarium that also contains marine algae growth of which they can graze upon. The Black Combtooth Blenny is becoming more popular within the hobby, but can sometimes be hard to acquire; it can be ordered through some local retails and may be found through various online vendors and other hobbyists. Black Combtooth Blennies require an established aquarium of no less than 30 gallons and should be provided with a sand substrate in addition to an adequate amount of live rock (live rock should be securely placed in case of burrowing) for grazing, perching, and refuge. A lot of Blenny species are known to jump if startled and they should be housed in an aquarium with a hood or sealed top to prevent escape. Quality biological and mechanical filtration is recommended, along with the use of a protein skimmer to help ensure stable and clean water. As a peaceful species they will get along relatively well with many different tank mates, but may argue with conspecifics and species of a similar appearance; multiple specimens in the same system should already be a pair, or at least introduced at the same time (as juveniles). Black Combtooth Blennies are not aggressive and should not be housed with aggressive or highly territorial species that will constantly harass and force them into hiding. Although considered to be reef friendly, this species has been known to nip at various corals as well as clam mantles. The Black Combtooth Blenny is a herbivore that loves to graze on marine algae in the wild. The species will also graze on existing marine algae within the aquarium (ornamental and nuisance), but should also be provided with a wide variety of live and prepared marine algae, vegetable matter, and Spirulina-based flake and pellets foods (preferably treated with Selcon) as well as other prepared foods for herbivores.

The Starry Blenny gets its name from its dark brown base color with multiple white to light blue dots over its entire body; they also have bushy cirri (whisker-like appendages) protruding from between their eyes, are equipped with combed teeth for algae grazing. The Starry Blenny prefers a well established aquarium containing various strains of marine algae along with stable water parameters. The Starry Blenny likes to perch on live rock and corals between grazing to make sure it doesn't miss anything going on in the aquarium. They are a hardy and intelligent species that will add personality to any system along with the added benefit of controlling nuisance algae growth. Starry Blennies are a popular choice for "nano" systems as well as larger community reef setups and will get along peacefully with their tank mates as long as they do not have a similar appearance; they are readily available within the hobby at very reasonable prices. The Starry Blenny requires an aquarium of at least 30 gallons and should be provided with plenty of live rock for grazing, perching and hiding; the live rock should be stable as Starry Blennies will sometimes dig and move rubble and other objects around which can dislodge structures and can lead to injury. Blennies are also known to be excellent jumpers, so a sealed or secure top is recommended for their environment. They are peaceful bottom dwellers, but they been known to be territorial with other Blennies, small Gobies, Dartfish and species that have a similar appearance. They are considered to be reef-safe, but have been known to pick at the mantles of clams and LPS corals when underfed (this is much less common in larger systems). The Starry Blenny is a herbivore and grazes on various marine algae within its natural environment. In the aquarium it should be fed a variety of vitamin-enriched marine algae, vegetable matter, and quality, Spirulina-based prepared foods. It will also gaze upon ornamental and nuisance micro/macro algae that may already be present in the aquarium. Feed twice per day.
