So has anyone else tried this? I happened to get the brilliant idea to try to get my new Betta (currently named "Fish" from a lack of inspiration) to play with a laser pointer I have. You know how you always see Pet stores selling laser pointers for cats and dogs to play with. Well, I tried shining the laser dot against the dark wall of the tank and the cave. Fish seemed to enjoy chasing it around trying to bite it. He didn't act threatened by it at all. Has anyone else tried this?
