This fish is always swimming around and I haven’t had any issues with it being aggressive. It is in a 125 gallon so idk if that’s what helps with its temperament but it has been a model citizen fish.

They can pick on smaller tank mates, but usually it’s not an extended problem. They have really great color and look beautiful under all types of lights
