So how bad are hydra? I have them in my 10gal cherry shrinp tank. Could they kill a small cherry shrimp? I think they came with my eco-complete. So far I have seen nematodes, copods, and hydra in this tank and the only explanation I find is the eco-complete substrate. I have never seen any of these in any other tank with the exception of copods in my 40gal, that also has eco-complete.
