(Paracheirodon axelrodi) Moderate Peaceful 2" 10 gallons 74-84° F, KH 2-6, pH 3.0-7.5 Omnivore Venezuela, Brazil, Amazon Characidae Tetras Community The Cardinal Tetra (Paracheirodon axelrodi) originates from the rivers of Venezuela and Brazil, where they are found in a variety of river habitats ranging from slow-moving forest streams to minor river tributaries. Their native habitats also range from areas with substrates covered in leaves, branches and tree roots to areas with clear water, sandy substrates and dense growth of aquatic and bog plants. Despite still being collected in the wild, their immense popularity within the aquarium hobby has led to extensive breeding programs that breed large numbers of specimens for the commercial trade. Despite being very similar in both appearance and maintenance requirements as the Neon Tetra (Paracheirodon innesi), the Cardinal Tetra (Paracheirodon axelrodi) is a separate Tetra species. Neon Tetras are a little smaller, usually a little cheaper, and typically a little hardier than their Cardinal Tetra cousins. Cardinals are a little more bold in appearance, mostly because they have more red on their lower sides. Both are schooling species that like to be in a group of at least six or more individuals. Mixed groups of Neons and Cardinals will also readily school together, with the bigger the school, the better they tend to look. Due to their small size, Cardinal Tetra can be comfortably housed in small aquariums and even nano tanks. However, they do best in schools of 8 or more individuals and aquariums of at least 20 to 30 gallons or more. As is the case with most small fish species, stable water parameters are very important. Quick fluctuations of water temperature, pH, etc. can shock the fish and cause them to be more susceptible to stress related diseases or even cause death. The ideal tank conditions for Cardinal Tetra will include: stable pH & water temperatures around 80° F, low to moderate water flow, plenty of both tall and ground cover vegetation, tree root or driftwood and peaceful community fish tank mates. The Cardinal Tetra is one of the most peaceful species available within the aquarium hobby. They do well in any peaceful community aquarium containing small to medium community fish species and non-predatory medium sized Cichlids. Larger Cardinal Tetra can typically be successfully kept with larger community species like Angelfish, Discus, Gourami and other similar species. Keys to successfully keeping Cardinal Tetra with larger community species include: keeping them in groups of eight or more individuals, providing plenty of vegetation or other suitable cover, providing adequate space in the aquarium (prevent over crowding) and keeping their larger tank mates well fed. In the wild Cardinal Tetra feed on a variety of items including: small invertebrates, small crustaceans, insect larvae, filamentous algae and other similar fare. Being an omnivore, hobbyists should provide a mix of algae, vegetable based and meaty foods. Quality commercial flake, freeze-dried or frozen foods make an excellent staple diet. Hobbyists should also mix in items like bloodworms, daphnia, baby brine, etc. in order to vary the diet and provide a balanced diet. It is best to feed small amounts of food 2 to 3 times per day and occasional abstain from feeding for a day or so from time to time.

(Inpaichthys kerri) Easy Peaceful 1.5" 20 gallons 76-82° F; pH 5.5-7.0; dH 1-12 Omnivore Brazil, Amazon Characidae Tetras Community The Blue Emperor Tetra (Inpaichthys kerr) are is an attractive Tetra species originating from the Upper Aripuanae and Madeira river basins of the Brazilian Amazon. Their brilliant blue / purple coloration makes them a stand out species in the tropical freshwater aquarium trade, as there are not too many other species that exhibit a bright blue / purple coloration like the Blue Emperor Tetra. They are commonly sold within the hobby under a variety of common names including: Purple Emperor Tetra, Inpaichthys Tetra, Blue Emperor Tetra, Regal Tetra and Royal Tetra. They are also sometimes mistakenly sold as Emperor Tetra (Nematobrycon palmeri), but they can easily be distinguished as they possess an adipose fin unlike the Emperor Tetra. Blue Emperor Tetra have a very peaceful disposition, thus they should be housed with other small to medium sized peaceful community species. They do best when housed in groups of 6 or more individuals in a well planted aquarium that emulates their natural Amazonian habitat. Ideal tank mates include: other Tetra, Hatchet Fish, Cory Cats, Rasbora, Gourami, peaceful Barb species and some smaller Cichlids like Rams Cichlids. The Blue Emperor Tetra will have a difficult time competing with boisterous species like many Barb species and Danio species for food and territory. Also do to their small adult size, the Blue Emperor Tetra is not well suited for aquariums with Angelfish or larger Shark or Catfish species who will often eat the sleeping Tetra during the nighttime hours. The natural river habitat of the Blue Emperor Tetra is comprised of slowly moving river tributaries that with leaf covered river bottoms, plenty of tree root structures, filtered light from the jungle canopy above and a soft sandy river substrate. The waters of their natural habitat are also stained a brown tea color from the fallen leaves of the jungle canopy above. Ideally aquariums housing Blue Emperor Tetra should have areas containing root structures, some vegetation, diffused lighting in some areas and low to moderate water currents. While this species can adapt to a variety of tropical community aquarium habitats, they should be provided with some key elements of their own natural habitat. Most importantly some areas of the aquarium should contain wood root, plants and low water currents. Aquariums with darker substrates and dense vegetation will help bring out the brilliant blue and purple coloration of the Blue Emperor Tetra and provide them with a good sense of security. Blue Emperor Tetra are an omnivorous species that will readily accept a variety of flake, crisp, freeze-dried, frozen or live foods. A typical tropical species staple flake will satisfy their complete nutritional needs; however, they can be offered bloodworms, brine or other similar foodstuffs to give them some variety in their diet. Ideally the Blue Emperor Tetra should be fed 2 to 3 times per day small amounts of food that they will consume within a 5 minute period.
