I got a little live rock rubble to put into my canister filter awhile about a month ago. I noticed about 2 weeks ago I had this hitchhiker, but am unsure what it is. I have left it in my canister filter and it seems to be surviving just fine. I dont know if it is reef safe, or should I put it in my mantis tank, or leave it in my canister? It is about 1 - 1 1/2 inches long. It has little hair like tenticles. I dont know if it is some sort of nudibranch, or cucumber. Maybe a seahare?
