My shrimp don't jump Shango. I've had them in the same tank for 4 years. I have just small tetra sized rocket killies and an oto. I do water changes two times a month maybe, or when it gets too much algae. Just a sponge filter and lots of plants and a big light. Maybe it's your water, filter or fish chasing them.

My tanks are all open topped and there is a pretty slow but steady stream of dried out fellas on the carpet. There are a TON of shrimp in there so it could be that it is just the odds that in so many there would be jumpers but if they jump because of some specific water issue or predator issue, I want to know.
