Yes they really are Electric Blue, especially as adults. Very easy and grows rapidly. Quite capable of reproducing in the tank. I keep endlers and shrimp with them though and they all seem to get along. These will tear up plants and eat them but some floating plants are possible. Just so striking by themselves or with a contrasting shrimp.. Loves snails and has cleaned up more than one of my tanks. I sell mostly sexed pairs butt ask and I may have larger or smaller ones available at around 2 inches at shipping and can get to 4-5 inches in a few months.
Amazingly rapid growth.
