ctenophore on Tyree Green toadstool?

[reeferoo]

So in 2008 I bought a Tyree neon green toadstool at a show (woot!)

It has very very rarely extended polyps, let alone fully extended them or even had them out enough for me to enjoy the green. It is seriously like maybe 1" and has not grown a millimeter. I don't even have a remotely good photo of him cause he isn't one of my most attractive corals

I had read about toadstools closing up and shedding waxy skin now and then being regular.

I have a nitrate problem, so it is hard to tell what causes some of my corals to be less than happy- my bad params or something else.

I have been working hard to correct my water quality and I am always trying to put this leather in flow he likes (lots!)

Several times I have observed 6-8" tentacles (usually one or two, never more than two) coming off my toadstool. They have regularly spaced feathery splits and pictures and descriptions of ctenophore sound spot-on. I have not spotted these anywhere else in the tank.

So considering this may be part of the reason my toadstool is not happy but has still stayed alive, how can I get him off?

I have not been able to spot the source, but I didn't know what I was looking for before. If I can find this ctenophore (assuming that is what it is) can I pluck him off with tweezers without seriously injuring my toadstool?

Thanks for your input

It does sound like a type of ctenophore called a coeloplana. I've had several of them on leathers before with no problems. I guess if the leather is really small it could be an issue. How big is the frag?

IME, the green toadstools grow quite slowly, as compared to the regular kind ("Tyree" branded or not).

Many years ago I had a largish regular toadstool with a ctenophore whose tentacles extended several feet!

I'd guess you can just yank off the ctenophore's tentacles, although IIRC, they retract very quickly.

Personally, I'd rather have a cool ctenophore than a big green toadstool
