This variation of the Tetra Fish is very beautiful due to the splash of red across their face, the silver body, and the black and white striped tail. This is an non-aggressive fish that needs to be put in a community tank with other peaceful fish.

This is one of the most popular kinds of Tetra fish with aquarium enthusiasts around the world. The Neon Tetra has a bright blue body with a red tail and can grow up to 2 inches in length. The Neon Tetra is native to South American waters and prefers clear water with many plants and lots of low light areas where they can hide. .I have four of these Colombian Tetra in a 55 gallon tank, along with 6 black skirt tetras, 4 flame tetras, a dozen cardinal tetras, 6 large red swordtails, 2 plecos, 5 green corys, and 4 long fin zebra danios. The tank is well planted with living bunch plants (anacharis) and bushy artificial plants, with plenty of room for swimming above the plants. They have behaved themselves well, no nipping or harassing the other fish. Fed a variety of flake, frozen, and live (adult brine shrimp) foods. Three of them appear to be 'filled out' and I think they are females. I'm going to try to move them outside this spring in an artificial pond to see if they'll breed.The rummy-nose tetra is a torpedo-shaped fish, whose basal body colour is a translucent silvery colour suffused in some specimens with a greenish tint: iridescent green scales are frequently seen adorning the fish at the point where the fontanel (a part of the head roughly corresponding to the forehead in humans) meets the body. The fins are hyaline, with the exception of the tail fin, this fin being adorned with black and white horizontal stripes, variable in number, but usually comprising one central black stripe in the central portion of the tail fin, with two horizontal black stripes upon each caudal fin lobe, the spaces between the stripes being white, the total count of black stripes being five. The head is a deep red colour, iridescent in lustre, with the red continuing into the iris of the eye, and some red colouration extends beyond the operculum or gill plate into the anteriormost section of the body proper. Some specimens classified as possess three black tail stripes instead of five, and some specimens classified as have a black stripe in the caudal peduncle extending forwards into the body, surmounted above by a thin iridescent gold line: however, whether these features are reliable determinants of species identity has yet to be fully ascertained.Some species of tetra are easily confused with each other. Neon tetras, commonly sold in fish stores, are often confused with glowlight and cardinal tetras. Cardinals and neons have a blue stripe that runs from nose to tail, while glowlights have a yellow-green stripe. All three species have red tail markings accompanying the stripe; neons' and glowlights' stripes run from belly to tail, while cardinals have red coloration over the majority of their lower bodies.A planted aquarium of at least 30 gallons will be the ideal environment for the Red Tail Mirror Tetra. Rocks and driftwood help mirror its natural habitat and will help to reduce stress on this fish. This species does best with soft, slightly acidic water with high filtration.The Red Tail Hemiodus Tetra (Hemiodus gracilis) is also referred to as the Slender Hemiodus, or Red Hemiodus Tetra by tropical fish keeping enthusiasts, and is found in the floodplains, rivers, and lakes of Venezuela, Guyana, and Brazil, South America.
