haha good question....I have a fish myself and he seems to never sleep! But every now and then I will catch him in the corner of his tank moving back and forth slightly but remains in the same spot, this means that they are sleeping. Fish are never completley still when they sleep, and never close their eyes (if they even have eyelids....D: ) hahaha this is just a survival technique for them.....hope this helped :)
