I currently have 3 BBGs, and plan to get cherries in the near future. I do know that shrimplets are a tasty snack for BBGs, and they might also go for juvs as long as they fit in their mouth. My 1.5ft has quite a lot of moss and hiding places, and I'm planning to get subwassertang to increase those places. Was wondering, has anyone ever successfully setup a mini ecosystem, where the breeding of cherries is substantial enough to feed BBGs as well as sustain their own population number?
