Right now I have 6 margarita snails and 6 red scarlet reef hermits. I am planning to get 2 percula clownfish and a royal gramma. The other fish I am not sure of yet. Are any of these predators to it?
yes---the clowns might eat the pods, and the royal gramma will definetly eat them
you might want to have some sort of rubble pile for the pods to live in--something innaccessible to the fish
btw, great choice for fish for your zoo reef
