Hes stressed imo all fish do this as far as i know! What do you feed him? whats temp? Are there any other sharks?

My harlequins and pleco loose their colour at night but once the lights have been on for a while they're back to their bright old selves.

Water temp is the same as always 75 the there are no other sharks in the tank just a few neon fish, a small molly, african leaf fish and a eel
