Only ever had one peppermint shrimp, harassed my shrooms, and some stuff just didn't look happy after adding. Been in the hobby 5 years now and still haven't had a cleaner, I need to get my priorities right lol, I really want one.I don't trust them. I've read too much about them tearing apart LPS. I had some thing (I think it's my skunk cleaner) that just tore apart my favorite blastos. Just the mouth was taken out when I woke up one morning, nothing else. The skirt is still hanging on with color for one of them, moved it to shadiest no flow area of the tank.
