ctenophora on trachy? Harmful or harmless?

[Reefkeepers Archive]

For some context, I just picked up a trachy yesterday, gave it a iodine dip and placed it in my tank. All seemed well, then I noticed 2 feathery appendages protruding from the trachy. At first I thought they were sweepers, so I moved it a bit farther away from the Lobo. However, i looked at the tank tonight and saw them again, there around 8-12 inches long. And only 2 are present still, they have branches coming off the maim stem, concerned for my lobo, I did some research and found this Reed builders article discussing a similar thing

So naturally, I need your thoughts. Are they harmful, should I remove them, will they sting/irritate my lobo? Here's a photo

Sorry for the bad photo. They're very thin and my camera isn't that good

If that thing was in my tank it would have multiplied into the billions before I would have noticed it. I don’t think it would do that in your tank but if it does it might be really bad.

I would expect that it would feed on small plankton items, if you don’t have a lot of micro fauna I would expect it to starve.

The article says that some eat small fish so if that is one that does I would worry that it has a potent sting in the tentacles.

I doubt that it is a problem but I would observe it to be sure, and jettison it if it is.

Edit:Thanks for posting this. It is something new.

Either way if you didn't introduce it on purpose I would remove it if at all possible, yes it may die off. But the possibility of it reproducing and causing problems down the road is something you don't want to deal with.

Any idea on how I would go about removing it?

Decided to remove it just now, I used a paper towel to wipe it off, it was surprisingly on the tissue and not the skeleton, which made it easier on my part, I hope they're not like aptasia, don't want them spreading from a single cell
