playing with your fish with lasers
Does anyone else use laser pointers to mess with their fish? I can get my whole shoal of 18 tiger barbs to chase the dot, in another tank my Oscar tries to eat it, my friend's black tetras follow it and my old roommate's african cichlids would too. The only fish that don't seem to follow it are catfish, my harlequin rasboras, and my shrimp don't follow it either. I think my snails might be following it too, but I'm not patient enough to find out.
