I went out and bought a laser pointer for my two cats. Turns out my fish like it too! I made a short video of my guppies chasing it, and I'm hoping to get one of my cichlids too; it's so funny! http://www.youtube.com/watch?v=GzAZGtKtbBs&feature=youtu.be And now I want to see your fish chase lasers! Ready... go!
