Well, I have 7-8 of them ordered up! They just better be the kind that love aiptasia. Everyday I am nuking the darn things. Next morning I find 6 or more of them...that I can see anyway. We never had them in our 180G tank, and we brought in new coral, fish, rock, you name it. I'd see one, nuke it and that was the end of it. They are definitely lethal to seahorses if one attaches to one and you don't see it right away, or they get very sick if they accidently rest on top of one of those nasty things! That's very scary stuff! So I'm up to my pits in the tanks daily nuking these things. I just keep telling myself that soon I will have the peppermints. I hope they come hungry!!
