Note: Your item may not look identical to the image provided due to variation within species. Their timid nature, however, may make them not suitable for typical community aquariums that have overly rambunctious or competitive species. Pristella tetras are extremely peaceful and rarely conflict with tank mates. Their natural habitat does not feature aquatic plants, but Pristella tetra are a common species selected for live planted aquariums. The aquarium does not need to be aquascaped with anything in particular to keep a shoal of Pristella tetra happy, but a darker substrate, leaf litter (almond leaves), driftwood and other natural-looking arrangements will bring out the beauty of this tetra. Pristella tetra are a very adaptable species to a wide range of water parameters. Pristella tetra are one of our listed “hardy fish” because they are able to endure the initial break-in cycle of a newly set-up aquarium. Size up accordingly to accomodate a larger shoal. Variety is the spice of life in order to maintain color, immune function and longevity of your fish.Ĭare Requirements: A minimum 5 to 10 gallon aquarium is ideal for a small group of Pristella tetra. Nevertheless, offer a diet made up of various high quality vegetable based and protein based flake foods, sinking micro pellet foods and bug bites, in addition to offering frozen foods such as bloodworms, brine shrimp and daphnia. An adult Pristella tetra can reach a size of approximately 1.5″.ĭiet Requirements: Pristella tetra are among some of the most unfussy with regard to food. Pristella tetra are natural shoaling fish, thriving best with at least 6 individuals but more are encouraged. While overall plain in color, the yellow and black detail in the dorsal and anal fins of the Pristella tetra adds quirk to this species. One of the hardiest and inexpensive tetra, the Pristella tetra makes a great choice for the beginner hobbyist. Due to its popularity, all Pristella tetra available within the aquarium trade are captive or commerically produced. The list below is incomplete.General Description: The Pristella Tetra has a large distribution throughout northern Brazil, Venezuela, and Guyana. Since the aquarium trade may use a different name for the same species, advanced aquarists tend to use scientific names for the less-common tetras. Īlthough the list below is sorted by common name, in a number of cases, the common name is applied to different species. Ichthyologists debate the function of the adipose fin, doubting its role in swimming due to its small size and lack of stiffening rays or spines. While this adipose fin is generally considered the distinguishing feature, some tetras (such as the emperor tetras, Nematobrycon palmeri) lack this appendage. This adipose fin represents the fourth unpaired fin on the fish (the four unpaired fins are the caudal fin, dorsal fin, anal fin, and adipose fin), lending to the name tetra, which is Greek for four. Additionally, tetras possess a long anal fin stretching from a position just posterior of the dorsal fin and ending on the ventral caudal peduncle, and a small, fleshy adipose fin located dorsally between the dorsal and caudal fins. They ordinarily possess a homocercal caudal fin (a twin-lobed, or forked, tail fin whose upper and lower lobes are of equal size) and a tall dorsal fin characterized by a short connection to the fish's body. Tetras generally have compressed (sometimes deep), fusiform bodies and are typically identifiable by their fins. For example, payara ( Hydrolycus scomberoides) is occasionally known as the " sabretooth tetra" or "vampire tetra". Even vastly different fish may be called tetras. It is short for Tetragonopterus, a genus name formerly applied to many of these fish, which is Greek for "square-finned" (literally, four-sided-wing).īecause of the popularity of tetras in the fishkeeping hobby, many unrelated fish are commonly known as tetras, including species from different families. Tetra is no longer a taxonomic, phylogenetic term. Consequently, they are extremely popular for home aquaria.
Many of these, such as the neon tetra ( Paracheirodon innesi), are brightly colored and easy to keep in captivity.
The Characidae are distinguished from other fish by the presence of a small adipose fin between the dorsal and caudal fins. Tetras come from Africa, Central America, and South America, belonging to the biological family Characidae and to its former subfamilies Alestidae (the "African tetras") and Lebiasinidae. Tetra is the common name of many small freshwater characiform fishes.
