Tetra is the common name of many small freshwater characiform fishes. 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. The Characidae are distinguished from other fish by the presence of a small adipose fin between the dorsal and caudal fins. Many of these, such as the neon tetra (Paracheirodon innesi), are brightly colored and easy to keep in captivity. Consequently, they are extremely popular for home aquaria.
Tetra is no longer a taxonomic, phylogenetic term. 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).
Because of the popularity of tetras in the fishkeeping hobby, many unrelated fish are commonly known as tetras, including species from different families. Even vastly different fish may be called tetras. For example, payara (Hydrolycus scomberoides) is occasionally known as the "sabretooth tetra" or "vampire tetra".
Tetras generally have compressed (sometimes deep), fusiform bodies and are typically identifiable by their 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.[2] 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. 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.[2] While this adipose fin is generally considered the distinguishing feature, some tetras (such as the emperor tetras, Nematobrycon palmeri) lack this appendage. 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.[3]
Although the list below is sorted by common name, in a number of cases, the common name is applied to different species. 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. The list below is incomplete.

Tetra es el nombre común de muchas especies pequeñas de peces de agua dulce, muy utilizados en los acuarios que comprenden a las familias Alestiidae, Characidae y Lebiasinidae.

En zoologie, et plus particulièrement en aquariophilie, le nom vernaculaire tétra désigne plusieurs espèces de petits poissons d'eau douce originaires d'Afrique, d'Amérique du Sud et d'Amérique centrale, pour la plupart de la famille des Characidés. Ils sont appréciés en aquarium pour leur petite taille, leur comportement intéressant et leurs faibles exigences.
Le terme « tétra » n'est pas exactement un taxon phylogénétique en ichtyologie. En raison de la popularité des tétras en aquariophilie et en pêche sportive, de nombreux poissons indépendants sont communément appelés tétras, y compris des espèces de différentes familles. Même certains poissons très différents peuvent être appelés « tétra ». Par exemple, Hydrolycus scomberoides est parfois connu sous le nom de « tétra vampire ».

Les characidés se distinguent des autres poissons par la présence d'une petite nageoire adipeuse entre la nageoire dorsale et la nageoire caudale.

테트라(Tetra)는 아프리카테트라과, 카라신과, 레비아시나과에 속하는 작은 담수어 종들의 총칭이다. 몸길이는 5-8cm로 빛깔이 아름다워 애완용 물고기로 인기가 있다. 네온테트라는 몸통의 옆면에 선명한 푸른 줄무늬가 있고 금낭화테트라는 몸통의 옆면 중앙에 선명한 반점이 있다. 진홍테트라는 몸통과 배가 짙은 붉은색을 띠며 다이아몬드테트라는 밝은 은빛을 띤다. 남아메리카와 아프리카가 원산지로 1,500여 종에 이른다.
