Comb jellies everywhere! What to do?

[kelp47]

So I have what I'm now calling an infestation of comb jellies. First I had just one in my display (that I knew of). Then it ended up in my overflow box and turned into a couple dozen. Now they're all in my sump. I probably have well over a hundred.

I've read they don't sting, so I'm not worried about that, but they eat a lot of pods. Should I be concerned that they will eliminate my pod population? Should I do something about them?

Are you sure they're comb jellies? Can you post pics? 'Cause I doubt they're jellies, they're probably hydroids.

Here is a photo I posted when I spotted the first one in my display. Someone else told me it looked like a comb jelly; and when I looked it up, it's seemed right. It's hard to photograph them in the overflow and the sump, so this is probably the best shot I'll have. Though I can try later if you need more.

Just keep them away from your coral and they won't hurt anything.

I can't seem to find a comb jelly in the picture provide (Honestly idk what I'm looking at! A plant?)

In order for you to really see it, I had to get a photo with the aquarium lights off, and a light behind the tank on so that the jelly is backlit. That is my gorgonian, and the jelly is on the far right stalk. Its tentacles are flowing off the right side.

Ya definitely comb jellies. He's talking about the long stringy things coming off of the 'plant'.

So any advice on what, if anything, I should do with my hundred or so jellies?

Do they move like in this video? Anyways mine never bothered anything but I never had more than a few. I guess I would not worry, just if it were me. Sorry I do not know a good way to get rid of them.

I had the same problem. Finally solved it though. First, cut back on phytoplankton and zooplankton feeding. On, and no, I do not believe the ctenophores will eat your pods. Mine never did, and I had some over a foot long. Have you watched them at night? Tha rainbow shimmer is quite beautiful and mos hobbiests will never see it... So enjoy.
Now, back to wiping them out. Cut back on feeding your filter feeders. If you must, you can target feed them, but do not dump the filter food into the whole tank. Also wet skim. Also, whenever you can remove the ctenophore ( comb jelly) manually. You can get plastic disposable pipettes from amazon for $1 or less. They are great with lots of uses. They are basically like very small turkey basters. If you keep squirting tank waster at the edge of the jelly he will peel off whatever he is attached to, then you can suck him up and toss the pipette. You can weaken them by cutting off their feeding tenticles too.
This has worked for me and I had a serious tank full.
