What is this

Looks like a hydroid jelly fish to me, they sting, so not a good guy... our live rock has all kinds of critters living in and on it, which is why it's called live rock. If you didn't add it, it came as a hitchhiker.

which i have gad my fair share of hitchhikers, just never seen anything like this. nor have i heard of having hitch hikers appear 4 moths later. not only that but i have never heard of anything hitchhiking in on live stock. havent added live rock in over a year.

I first set up a 55 gal. 6 months later I changed over to a 125 reef. When I made the switch I found a HUGE black slug looking thing. We never did identify it on here so I kept it in the 125. Never saw it again. Strange how many cridders we don't see nor buy, but are there. lol

I had a case of hydroid jellies in my old 29 gallon tank. I netted all that I could see, but only after I (finally) found the colony was I able to get rid of them.

Did it look like this? Big picture is a top/side view. The small picture is a bottom view.
