My tank has been setup for about 7 months. I recently purchased a cabbage leather and now I've noticed some flatworms on it. They look to be the acropora eating worms maybe. They appear to be small brown circles. I haven't seen them anywhere else. The only other corals I have are a branching hammer and some yellow colony polyps. Would it be a good ideal to treat with flatworm exit now, or I was thinking of getting a six line wrasse, and have read it might eat them. If they are AEFW will they just die off since I don"t have any acropora? Thanks in advance for any advice.
