I was wondering if it would be ok to keep shrimp in the bottom of a canister filter to help eat food from the messy eaters in the tank that would eat the shrimp otherwise. I figure they would be extra filtration. I tried finding info on it but it just seemed to be of people finding snails and shrimp in the canisters growing and living but they remove them and I want to keep them in there full time for clean up if that is possible. The filter is a sunsun if that matters. My plan would be to keep them in there eating and populating and if there got to be to many turn them into fish snacks I was thinking ghost shrimp or rcs.
