I found some eggs in my tank. Can i move the rock they are on into a bucket for cleaning? or should i just do water changes? the water is about 70ish and the pair are only one inch. They dug a really cool tunnel under the rock. so i don't want to piss them off by moving all the stuff around again on them. oH and i have a black F left in the tank... should i move him out? his just hidding right now and eating. no known problem but when he get close to there cave he gets chased off.
