Does anybodies SAE lose its black stripe at night? Often when I come home late the black stripe has faded considerably, only to return in the morning. He is well fed off algae disks and flake food, and the water parameters are all normal. He's in a 20 gallon with some plants, 2 platies, 3 danios, and a cory. Let me know any suggestions because I know that they can lose their stripe when they become stressed. Maybe he's scared of the dark? haha
