So since I have moved into an apartment and my tank lights go out quite early I have run into some problems with my foxface freaking out after lights out if any lights around the tank are on. I was trying to think of a sort of ‘cover’ for the tank to protect it when the lights are off. I thought of a towel but I don’t think there is one big enough. Tank is 4x2x16 and figured someone on here has a better idea then a towel. What does everyone else do to keep their fish happy after bedtime regarding lights around the tank?
