So I always thought these things were found with inverts. I saw a bunch of tanks living with shrimps with them. Today, I bought a cleaner shrimp, and when it went into the lemon peel, it took a few nips, not sure whether it was just a bully or what...So from the overflow it wouldn't leave so I showed it to the other side of the tank and the jawfish flew out and hit it twice. I don't know if it was just territorial or what. The shrimp has gone to another corner and is doing nothing but sitting there now. And now hides beneath my float
