The red-eye emperor tetra ( Nematobrycon lacortei ), also known as the rainbow emperor tetra or rainbow tetra , is a tetra native to western Colombia . It becomes up to seven centimeters long and lives in smaller flocks . In this case, it is much more aggressive than the also in the genus Nematobrycon derived Nematobrycon Palmeri ( N. palmeri ).
In the red-eye emperor tetra, the longitudinal band is less pronounced in the drawing than in the emperor tetra , the body color is less clearly delineated overall. The animals are well suited for keeping in aquariums ; however, the minimum pool size should be at least 1.20 to 1.50 × 0.50 × 0.50 meters, depending on the size of the group. If the light falls through the floating plants contained in the pool , the iridescent blue shimmer of the spotty drawing comes into its own. In contrast to the smaller females, males have a red iris and an extended central caudal fin ray. The species reproduces as a permanent spawner.
