I have a small aiptasia problem and I want to introduce a peppermint shrimp. I already own a coral banded shrimp and I am wondering if they will fight. I have a 6-foot tank and it is 1 foot wide, there's enough space for them to stay at opposite ends. I also want a cleaner shrimp so it can clean my fish. Can I add more shrimp or my coral banded will kill them
