I had great success with peperment shrimp also but they are hit or miss. I had two tanks a 65g and a 75g. I had problems with aiptasia in my 65g and tried the pepermints - worked great. They were gone within days. So a few months later I started to have problems in my 75g, I purchased more (same vendor) they might have eaten a few but not really.
A buddy and I decide to go in armed with kalkpaste. We got 90% of them but they were under control (watch your pH - it will raise). Then each week I did a little more and before long (3 weeks or so) they were all gone. Please the main thing is not to get a fish or any living creature just to do one thing, make sure you really want it. With a little elbow grease you can get rid of them. I really like the shrimp so I didn't mind getting more, just disapointed they weren't consistent.
FWIW - I did move some of my rocks that had aiptasia from one tank to the other over night and the shimp at night would have a field day - in the AM I just put the rock back into its proper place. That actually was fun to do .
Well... the problem with pep shrim is that i also have a pseudochromis in my display tank. Won't teh peseudochromis take them out?
ReefD.. don't get me wrong. I have used joes juice MANY times before with plenty of elbow grease. I was just looking for a preditor to help me MAINTAIN their eradication. I've obviously never gotten all of them.. because they keep coming back.
SnowMan - Completely understand about the elbow grease, been there in the trenches. A buddy of mine and I had to spend a good two hours kalk pasting the heck out of them. We of course didn't get all of them but the next week I had to do it again, then the following week . . . after that etc. Once I was clean (I thought anyway) I looked the best I could in the back and there they were!!!! The one thing was I could keep them "under control" and really that was my main objective.
As far as the pseudochromis, I don't have experience with them but as my understanding from my friends that do - they haven't had a problem at all. I really don't think they would be any worse than my larger wrasses (I could be wrong on this).
Don't get me wrong - CCB are great but you'll be taking a chance. I really - really would like to have one but I just haven't made up my mind if I want to take the chance. Might have to find one that someone local no longer wants - Mmmm if they didn't have problems . . . .
