inverts and snails will eat them..........but if you want..............any shrimp species would do the trick.......but probably more active ones like Amanos........and tigers............I'd do tigers as they multiply/breed in FW unlike amanos...........so you can start selling them eventually. And you could add a diff. neocaridina speicies like RCS or yellow shrimp as they will also multiply/breed but won't cross breed with caridina species like tigers.......for snails......idk, any type would work
