The most popular type of tetra fish, the neon tetra, requires a 38-litre tank. The beautiful fish have fins of blue and red and seem to shimmer as they swim. The neon tetra fish do best if there are at least six of them which can form a school. When you fill your aquarium with neon tetra, give them spots to burrow and hide, such as plants or rocks. Neons eat high-quality food flakes or brine shrimp. The neon tetra fish are easy to care for, but keep them in a tank with fish of the same size for the best results.
Another common type of aquarium tetra species is the cardinal tetra. They have bodies that look striped with bold blue and red shades. The eye-catching fish are peaceful, and prefer a 38-litre tank to live in. Put many plants in a tank with cardinal tetra, because they like to swim among the leafy plants. Keep lights low in your tank for the cardinals, and feed them flakes or pellets. The cardinals do not get very big, so mix them with similar sized fish for a gentle aquarium experience.
