I have 2 diamond sleeper gobies cleaning the bottom of my tank. One of them is always out and about just hanging out at the bottom, but the other one is always hiding. I'll see him about every other day or so. Is that normal?
The only other fish I have in the tank right now is a blue damsel (not aggressive at all) and a green Chromis.)
