About 6 months ago I noticed one of these little guys. Now, I think I've counted 8. They're really small. The biggest one I've seen so far is maybe the size of pea. I havent noticed any issues among the coral or fish. But I reeeeeeaaally wanna know what it is!!! In the 6 months of having these things I still can't figure it out. Help please! (I also included a pic of my hermit, Muhammad Ali bc he's so pretty. )
