Red Laser Tetra (Hemigrammus coeruleus)

Among the most sought after species of tetra is Hemigrammus coeruleus. The species attains a maximum length of about 6 cm and look even pretty in the regular coloration – a bit similar to the well known glowlight tetra (Hemigrammus erythrozonus). But when the fish come in breeding condition, they look really spectacular! The males become so deeply red that one might think to see a different species. It lives in Solimões and lower Negro River basins.
