Another vote for the peppermint shrimp!
About a month after I started up my tank (46g), I spotted a little aptasia and tried plucking it out. Yeah... I didn't know better. About three weeks later when I noted TWO little aptasia sprouting out this time, I went to my LFS
store for Joe's Juice, but ended up with Blue Life Aiptasia Control instead. This stuff...
at the LFS
personally vouched for it, so I gave it a try. Great stuff. Just squirt the goo over the thing, and it's gone. I think all it is kalk
paste, but I'm not sure. Whatever it is, it works.
After nuking three of them with the stuff, I decided to get a peppermint shrimp. Ever since, I haven't had to nuke any. In fact, I've never even seen any since. It could be coincidental I suppose, but it seems odd that as soon as I got it, the little aptasia explosion stopped.
When I added the peppermint, I already had a skunk in there. They get along fine and stay at opposite ends of the tank. I've got a little cave that opens to the back of the tank that the peppermint quickly adopted as his home. Every once in a while, the two shrimp cross paths and the skunk usuaully chases the peppermint a bit but the peppermint is definitely the shyer of the two and goes scurrying back to his cave.
I'd get a peppermint - it couldn't hurt. They're pretty funny to watch, staggering around the tank like they've had too much to drink!
