Hi all. I haven't been here in a long time. I moved and went pico, so I am definitely not Monster anymore, but it's all good right? lol

So, my tank has been doing pretty well for a year or so now, aside from being pretty much empty because I lost my job before I could fully stock it. I do have this thingamajig in it though that I cannot identify. I'm part of another forum's that mostly dead, and have not gotten a positive ID on it yet. They suggested some type of worm or barnacle, but as far as I can tell, this thing has no openings or mouths whatsoever.

It's sessile, about a half an inch across at the base, bright pink with whiskers, growing, it has a slick, bumpy surface texture but does not appear to be porous. It's stony, not fleshy. It started out as a fleshy nub with three whiskers. If you touch the hairs, there's no reaction. It doesn't move at all. That sort of siphon looking thing at the bottom is new, but from what I can tell, there's no actual opening there. I have never seen it open or send out any tentacles or nets, etc like tube worms and such do. It's getting bigger slowly, and started at about half the size it is now about 9 months ago.

I don't have a macro lens, so I had to crop a larger photograph down to get this closeup.

It looks like a sea cactus of sorts :grinno:. I have dubbed it "Prickles." I have never seen something like this, so I hope it's not some common thing I should already know about...

Any assistance would be appreciated :D.

Hmmm interesting specimin... doesn't fit the description of anything I know of... If its hard I would assume some type of coral... the hairs could be fine particle filter feeders, or chemical warfare tendrils of some sort. Hard to say.
 
Thanks!

It's definitely hard. I guess it might be some sort of non-photosynthetic coral. It's growing on a piece of rock I bought from an LFS's unlit tank. Looks a bit like an Indonesian Chili Coral or a Fuzzy Carrot, but those hairs are the weird things... they don't look like sweeper tentacles, and the polyps on the other corals all had a distinctly flower-like appearance. I guess it could just be too small at this point, though. It is growing a siphon looking thing at the bottom like a flower tree has.

I have no experience with non-photosynthetic coral, though, so I'll wait for someone else to chime in.
