What fish (s) eat sponges? Or CUC that will eat them. I have lots in the display on 2 rocks with Rhodactis and palys. Some in the sump.
The sump is okay. But they are going to choke out some of my corals I fear. I think there are some wrasse that eat them? Can't get them until my lid from clearview arrives. I have a diy mesh but don't trust it.
