Hi everyone, I have like 3 emerald crabs, and I noticed only one of them have this like algae or hairy stuff growing on its back. Does anyone know what is that? should I be concerned? should I remove him?
On that note, would they eat seaweed? i’m concerned that they don’t have enough food and will nip on my corals.
Thanks
