I have a 125 mixed reef tank, with lots of LPS, acans, lobo's etc and some SPS.I have tried to be very careful to keep a watch out for aptasia when I get new stock in, but it's hard to catch them all. Whenever I find one I get it out as soon as I see any. I went for a long time without ever having any, but I have recently found some in my sand bed. I pick them out when I see them, but they seem to be multiplying. So I was thinking about getting a Copperband butterfly to help rid the tank of aptasia before it gets an upper hand. Has anyone here had any trouble with the Copperband eating your corals, either SPS or LPS? I'm very Leary of trying a Copperband, I'm afraid that I will end up regretting it when it starts munching on corals.
