Long Stringy Thing, I Fear the Worst

[Roboson]

Picked up a GSP frag a while ago right before my new tank "crashed". Now, a month later I notice these long stringy things. Sorry about the quality.

My initial guess would be hydroids?

Digitate hydroids
Remove ASAP these guys will take over

That would be my first guess based on the image provided.

Is it the same as this? I found it yesterday:

I have the first things-maybe 2-3 in the rock work. They come out at night.

@deaniscool, that does not look like a hydroid to me.

thanks!

thanks!

It could be root structure from caulerpa or other macro algae, but let others chime in.

If these are Digitate hydroids, is there a proper removal method?

Looks like digitate hydroids to me too but it might just be the image. Here's a good article. Does it look like these?

Not good. Get that out ASAP. I don't know of any tankwide treatments that won't kill all of your inverts and prevent you from adding them again.

I have had 8 out of 10 in these pictures.
I only have on rock I need to toss. and one other type I have is not pictured.
most went away. Not sure why.

There is a treatment that I have found. It uses fenbendazole

So let's assume mine are hydroids. I believe there to only be two of the buggers at this point. Will tweezer removal be sufficient?

IMO yea.
Mine just fell of and went away.
I may not be typical.

I think I'll just try and remove them manually then. Normally I wouldn't worry, but my tank has suddenly become very micro-fauna friendly (for no good/particular reason).

Yea I totally would. Tanks phase.
My yucky hydroids started to multiply on onenrock and the sponge and tunicates did too. Weird.
Throwing the rock in the yard this weekend.

Those digitate hydroids are a colonial animal if memory serves. I'm not sure pulling it out will do the trick since each segment is another animal. I don't think it would hurt though. Can you pull it off outside of the tank, maybe in a cup of water?
