so i noticed my marble angel missing. well i found him stuck in one of the holes in the holey rock. i managed to free him but he was looking pretty bad. got him put away alone and he might pull through. my question is why would my angel squeeze himself in there like that. hes about 2.5 inches and its a community tank so i know nothings picking on him. any comments will help. other then some blue rams and Colombian rams i havnt had any experience with angels this is my first one.
