Thanks for the input. The vids I see on youtube of epitoke makes them seem like they swim by wiggling the whole body more like an eel or fish, where as the one I saw in my tank only propel itself with the very end of the body.
I had already taken outs the one I saw swimming around last night. There were about 6 of them. Do I need to worry about them?
Right now I only have Zoas & Kenya tree in that tank along with some hermit crabs and snails. I had some other corals in that tank, but they have been moved to my bigger tank. We lost power from the storm, on the second day I moved all the corals, fishes, & shrimp into a large bucket and took them with me to my in laws. The temp dropped in the tanks from 80-65. After we got power back, I aquascape the tanks and only put the zoas and kenya tree back, the reset of the sps/lps went to the bigger tank. Not sure if the return of the normal temp or rescaping the rocks cause those buggers to come out.
