Pest growing, or not?

[BL1]

Ok, so I seem to have stumped everyone with my last thread ... so here's another one for you all. I've got this thing growing between the polyps of my zoas, Hopefully you can all tell from the pics. It seems to be soft and squishy to the touch, and when I tried to get the zoas to close so I could get a better pic of it and it closed as well...

They look like tunicates to me.

You've got yourself a zoanthid eating nudibranch there Brian.
Give those zoas a fresh water bath to remove the adult nudis and look for the yellow colored egg sacks on the rock around the base of the zoas.When find them,scrub them off with a tooth brush.

I was under the impression that it doesn't move around?

After going back and reading the actual post :D I think your probably right Biff.
I just looked at the pics the first time around:shock:

Damn, it's glued down to the rock. I can't just pull it out from between the polyps?
Those nudis, I get these things growing on my glass, they're white circles with yellow centers, are they the nudis?

If the thing on your zoas is a fancy little slug that moves around, then Yote is right -- it is a nudibranch.

But if that thing is stationary, stuck to the rock in between the polyps, then I think it's a tunicate.

Tunicates are not harmful. But nudis like that are, as they tend to specialize on one type of coral for their diet.

Well it definitely hasn't moved in the month that the zoas have been in the tank. And the zoas have been growing and doing well so hopefully its a tunicate

So this thread is pretty old but, I've been noticing that thing growing lately and it's keeping my zoas closed a lot now. Here's a new pic of it today and you can see how it's grown ... Also, I'm not sure if I said it earlier, but if I poke it it will close up.

And here's a bit of a close up

That's a type of tunicate for sure.

In fact, I bought the same kind from my LFS two weeks ago for my 90! :D

That's too bad, I would have given you this one for free :shock:. They're overgrowing my zoas :grumble:

The one at the LFS was growing really fast too. They had a bunch of pieces of PVC lined up, and it would grow from one piece to another, then they'd just sell the pieces of PVC. I never posted pics of it because I can't see through my glass! :lol:
