I traded off my snowflake eel and I am stocking my 10 and 20 gallon tanks with some of the fish that will go into my 75 gallon. I have a 3/4" clown and a 1' royal gramma in my 10 gallon tank right now. The royal gramma was just put in tonight which got me wondering... what is there night time behavior like. It seems like he rests on about anything he can with little fin movement, then he will swim around a little. Just wondering if he is ok? I will be stocking my 20 with 5 small green chromis.
