Oh yea. He has to go. I used to have many 1' fish they just disappeared. I first figured they found new holes to hide away in the 220. Now I know they were the first victims. I was just curious because I don't think this one is alone and the thought they could be in my 6 in sand bed is terrible. If you had an idea on sp then maybe I could get some behavioral info and size range to look for that's all. Thank you for all your help!I don't know what species that is, but it's probably not a coincidence that you've been trying to figure out what is chewing on your fish and then this beast shows up. I've actually never seen what the "regular ole ones" do to a fish's body, but I know mine loved fish and had power. He would haul it back to his den, to eat in private. Usually, I'm the first to say it's not THEE bobbit, but I'm going to say for the first time.... I don't know. Either way, I think he's a problem.
