I bought 5 bumblebee shrimp recently, and I put them in a 5 gallon fluval tank with 9 fish, I figure that those fish will greatly reduce any chances my bumblebees will breed. I have another tank, a 2.6 gallon Fluval which has around 35 cherries in it including shrimplets. However, that tank has hydra and a somewhat high GH of 120 ppm. What would be my best course of action for my bumblebees? It is important to note that I intend to begin a colony! and that I also have 3 black neos with them in the 5 gallon.
