snaisla re good, i have alot of nassarius snails and Strombus conches in my fuge to keep deterius down, astreas are good too, Hermits wille at the macros you want to grow along with anythign else they can catch, so no crabs or shrimp, fish mgith be ok, if you dont plan on usuny your fuge as a pod factory, alot of people have seahorses or pipefish in their fuge, they eat the pods and hand out in the macros, fuges are perfects enviroments for seahorses/pipes.
Cheatomorphia is the best macro you can get.
