Which one is a Kenyi? The two large ones came with the tank, one of their babies is here too, he's a little brown one. The two big one are kind of the bosses of the tank. The blue one is more chill, but chases for longer when one of the other fish bothers him. The orange one is kind of a jerk, in general. And what's the deal with the blue one spitting sand everywhere? He has built a huge mound of sand in the front of the tank doing it, idk why, but the peacock likes to rest in there, so I just let him do it. Def going to research the ammonia cycle though.
