Is it a bad idea to put a hermit or two into my filter sock area? We have a two yellow tangs, a naso, and a banner fish. They eat lots of nori. Some gets into the sump filter sock and plenty of their poop does too. Any reason why I can't put a hermit or two into my sump filter sock area for them to chow down? The sump is built so the hermits should only be confined to that area, three socks to move around to.
