Just to be on the safe side, it would be a good idea put the fish back in a clear bowl during the day so that it gets its normal light exposure. This is so that you don't cause any problems with the fish's circadian rhythm. [ The_MoUsY_spell_checker's advice column | Ask The_MoUsY_spell_checker A Question ]
