Silvertip tetra

The silvertip tetra (Hasemania nana) is a species of characid freshwater fish omnivores native to streams and creeks in the São Francisco basin in Brazil, but frequently kept in aquariums.[2] Silvertip tetras are slightly more aggressive than other comparable smaller tetras, observed occasionally to nip other similarly sized tetras.

Description

This small fish reaches up to 5 cm (2.0 in) in standard length.[2] The tetras are transparent with their gold colors and have a black stripe that runs along the mid to back section of their bodies. The males have brighters colors compared to the paler females. They are a social species of fish that can become territorial. They usually enjoy being with a school of their own kind.

The fish thrive in temperatures that range from 72°F - 82°F (22°C - 28°C). They live in slightly acidic waters that range from a pH of 6.0 - 8.0. They are common to find in pet stores and are relatively easy to care for. They can be affected by parasites and infections.

When they are preparing to breed, the male will be brightly colored while the female will be swollen. When they breed, the female scatters their eggs among vegetation while the male fertilizes them. The species have been known to eat their own eggs. The eggs will hatch after 1 and a half days.[3]
