This was on the floor of my coral qt. I have dipped all corals with coral rx and bayer (both once and just coral rx a second time 6-7 days later). I cannot find it any longer. There may be a second one that is not moving. Does this look like anything? Appeared to have a lighter colored portion.... maybe head? Thanks.
