Any ideas?

I have a bunch of these in my frag tank. No idea what they are good or bad. Anyone have any insight? Thanks

Those are flatworms .

Oh joy. Any recommended removal methods? Maybe a fish that would eat them?

Critter Identification: Red Planaria Flatworms – First Time Fish Keeper

Though these flatworms will not attack your coral or fish, they can reproduce so rapidly that they can block the light from reaching your corals, which can cause localised bleaching.

There are a few ways .
I went through this in my 230 gal for awhile .
You can make a diy siphon to remove them ( a piece of 1/4” airline running. To a nylon
As you suck them out they will go to the nylon and can be disposed of .
2) livestock
Although most will recommend fish such as wrasses the only for sure one that will eat them is blue velvet nudibranch

I added 1 Mel wrasse
2 six line wrasse
2) springeri wrasse
1) green spotted mandarin
And eventually found 2 blue velvet nudi which shortly after they were all gone

There is only 2 lfs I buy anything from and both claim to have never had flatworms .

needless to say I haven’t bought frags from either in a very long time .
I strongly suggest ! Dip and Inspect everything entering your system from
Now on

Red planaria flatworms. A Halichoeres wrasse or springeri damsel will be the best biological control.

Try to avoid chemicals such as flatworm exit.
It scares me to think if there are too many they will die and release toxins . I would assume too many in the system could nuke the tank

Thanks for all the responses. I think I’m going to try the fish method first since I have access to those the easiest. And also syphoning them out as well
