Just a couple I guess. I found a hitchhiker stomatella in there a couple days ago. I'm thrilled about that!!! I have a ton in my 8 gal and they do an excellent job of keeping everything clean. He totally cleaned up any diatoms I was having. On the other hand though, I'm getting some gha starting to sprout up all over. Trying to not get frustrated with that. I knew this could be a problem using that old live rock I had. So I need to decide what I'm going to do about that. I put in a bag of chemi-pure elite last night and I'll start water changes too. I have been saving frags and I'm anxious to get them in, but when I worked on looking up fmv for them I realized the coral budget doesn't go very far! So no big changes, just regular tank cycling stuff.
