Computer Mouse with Swimming Fishies

I’ve never been successful with having pets as fish, they cant seem to survive a month under my care. I either over feed them or under feed them, or they’ll just randomly commit suicide by jumping out of the tank. After some time I came to terms with the fact that fish and I dont mix. So it seems that the closest I’ll ever get to having fish as pets is in a computer mouse. Yep, there is something fishy going on with these USB optical mice, literally. The see-through mice are filled with liquid and swimming plastic fishes. They retail for $16.99 each.
