I have a 38 gallon reef tank. Coral is doing very well, but so is the Aiptasia Enemones. So I need to get rid of them. I have seen STOP AIPTASIA, or a sea slug called NUDIBRANCH BERGHIA and I heard BUTTERFLY FISH. Let me know what is the best way to get rid of them. I am not looking for a quick fix but looking at the long hall. thank you for your time.
