I purchased some corals off a fellow reefer and one of the shrooms came on a small piece of rock. Well fast forward about a month I guess he had an aptasia problem he didn't warn me about. On that rock there is about 2 large ones a 2-3 smaller ones. I have yet to see any anywhere else. Is it 100% that if they're on that rock there's bound to be some elsewhere? I have some aptasia-x coming in about a week. Should I just wait or take action some other way. What gets me too is the contradicting info online. Some say aptasia-x is great and others say it'll never fully eradicate the issue and they'll keep reproducing. Ive also heard the berghia nudis are good but not to get them for only a few (they're also really expensive). I'm down to try peppermint shrimp but have heard they are hit or miss. Just any advice Id love to here some opinions on what I should do.
