OK this stuff started growing over the summer and has done really well. I did not buy it and i do not know where it came from or what it is.
Can you ID it? Please and Thanks.

Oh wow... I've never seen that many. They are a little different than the ones I have in my tank.... I hope mine don't have the potential to get like that.

Cranberry, this stuff is very nice looking and is covering the rock nicely. Why would you not want yours to grow out? Is this something I should be worried about? I think it is really nice and was hoping it would spread to other bare spots.

i believe hydroids have a stinging capability like aiptasia and pest annenomies(sorry for the incorrect spelling) someone please correct me if i am wrong

Very strong stinging cells, especially once they begin the Medusa phase.
Search on Irukandji for an extreme example of this organism (The colony pictured is NOT Irukandji).

Its a reproductive stage where it forms a free swimming little jellyfish looking thing called a medusa stage. The pump up and down in the water column.

Well then I am not sure if that is what this is then. It is around some zoos and candycanes and even a monticap and nothing is showing any signs of any issues. It seems more like a nice growing rug of little pollops all connected..??.. Seems harmless and has been around awhile now.
Are you suggesting i start to try ot contol it or even remove it?? I almost want t cause it to spread to other areas.. so i am at a loss.
O yeah and as for the jellyfish looking things, never seen one in my tank.???

I am not, by any means, trying to tell ya what to do... just provide the information..... but those are definately colonial hydroids. They are very distinctive in their appearance. You may find them very attractive, but it doesn't change the fact they are stinging hydroids. You may not see the medusa stage just yet... sometimes you won't even see it. Those things are SUPER small. I only had 2 and they "disappeared" before I was able to take the "dime with the critter" pic. I kept a sundial snail tank because I thought they were beautiful... you could keep a hydroid tank if you wanted. But they will try to take over must of the LR real estate as time goes on....

My response isn't suppose to sound "snotty" in case it comes off that way. I've set up many tanks for nuisance hitchhikers. I happen to like them :)
