I think you already feel the if-maybe-wonder-thing etc. Sometimes these kind of things do work but usually not. Good Luck. I had a Cleaner shrimp for like 7 months a real pal to me and every one in the tank world. I was building up my fish in my tank and had a small 3 strips dams, tomatoe clown with a bubble anemone, etc. The cleaner would set up his station - clean outsides and in mouths the whole deal, I added a Rock Beauty angel and the next day the cleaner was in pieces at the bottom of the tank. They were supposed to get along too. By the way, the cleaner did get the chance to jump on the Rock Beauty ride and clean - Must have scared him to much. I would like to try another cleaner but then I would start to worry like you are now. I would say you'll be ok until you feed in one place in tank or add another item into your tank to cause a point of conflict. Again good luck.
