Please tell me this is not aptasia (pic included)

i can't find confirmed pictures of aptasia that look like these so I am hoping I am okay. Sorry for the poor picture quality.

IchHater · 02/09/2007, 08:56 PM

i have it too.

I am not for sure from the quality of the picture but I don't think it is aptasia. Does it retract when you touch it ?

Reeses · 02/09/2007, 09:22 PM

Look like this?

If they do, they are hydroids.

My tank has those too.

drummereef · 02/09/2007, 10:59 PM

Reese's pic is definitely hydroids. You don't want these. If you can isolate the rock they are on and remove them manually you might win.

bretdajet, those look to be hydroids but the pic is blurry.

Reeses · 02/09/2007, 11:01 PM

Nope, not in my tank. Just a pic from the net to help bretdajet ID it.

That is what they look like. It is ironic that the link Reesesput up talks about jellyfish because that is what my wife is calling them. Some of them are on a rock with a large polyp collony. Would I be okay to take that rock out of the water long enough to scrub all of these things off? They are begining to multiply pretty rapidly and are becoming a pest.

Looks like hydroids to me too. It would be best to get rid of them. They have a pretty potent sting and can spread to become a danger to other corals in your tank. I was able to contain an out break in my tank by covering the area with plumbers putty, but if you are able to pull the rock I'd give scraping them off a shot.

What would everybody think about doing a freshwater dip? Would that kill them? And would it kill all of the good things as well?

J. Montgomery · 02/10/2007, 11:38 AM

I've had a lot of success with pulling them out with tweezers. If they're in a big cluster then they'll frequently all come out in one pull. I had them spreading like wildfire at one point, after pulling out all the easily accessible colonies they've settled down and don't seem to be spreading anymore. Just a few colonies here and there, and I leave them alone.

I doubt that a freshwater dip would do the trick. Kalk paste is rather ineffective too.
