Aquarium Advice Addict
Strangely enough I discovered quite by accident while playing with the cats with a laser pointer, that if you focus the red light on the sand or gravel in a fish tank, the fish will chase it! My juvy cichlids go crazy trying to catch it! Obviously you still must be careful to not blind them. But the bonus is the reflection from the glass while playing with the fish, shows up on the carpet and the cats and fish play at the same time! I almost LMAO watching the fish chasing this laser pointer back and forth across the big tank. Fish aerobics.
