I moved mine around and everything turned out fine except I hurt my clowns fin so be very careful when moving your rock. It took him about a week to recover.
yeah colt grows extremely fast. My original colt I fragged it and then it split on it's own, now the frag is as tall as the parent and is splitting too. Soon I will have 4 Colts.
Today I noticed he is using both fins and it seems to be well again. I still havent seen him eat, but i guess he's eating something. How long can a fish live without eating.
