Arrow Crabs and Corals

[dmweise]

I have an arrow crab in my refugium to help with detritus that makes its way into the sump. I have been thinking that this may not be wise considering that it will also eat pods. I have heard that arrow crabs may eat corals. Is there any merit to that?

What would be a good refugium inhabitant? Peppermint shrimp?

Both of those are preditors and mostly opportunists. I would reconsider the arrow crab and keep the pep in the display as long as its a Wurdamanni, it should behave... This is a great pic...

I don't have any peppermints right now. They don't last long in my display tank. My hawkfishes love to eat them, as does my Marine Betta.
