Hey, I've been trying to get a pic of these nudibranchs I found in a sump tank on my frag tank. They are red and I took them to a trusted LFS to confirm they are in fact nudibranchs. They have a black spiral in their midsection, two antennae and are about 2 mm long at most. Needless to say, I've been having trouble getting a good pic, but I'm working on it. Anyone have any knowledge of such a nudi? They were all gathered together on a rock in one spot where there isn't anything, which made for easy removal at least. Closest I've found was one that feeds on macroalgae and I do have dragons breath in my frag tank, but none in the sump. Any help would be greatly appreciated.
