Any ideas?

Might be a stupid question and I apologize if it is, I know at the top of the flipper are sponges(which I believe are good) and small pods towards the middle but what is that big thing in the middle of the flipper? There are 3-4 of these on the flipper and I have no clue what they are. Thanks!

I'm a little lost here. Is this something that came in on a fish? A little background information would be helpful.

Looks like a slightly misshapen pineapple sponge

Didn’t come on a fish, it’s no where else in the tank beside behind the flipper(I think), did a little more research, possibly a pineapple sponge?

Any chance you could get a pic with white lights only?

sponge, or if it's moving then I think planaria worm.

Better picture? @ChgoGoodGirl

the one on the photo (bottom left), look like pineapple sponge, the bendet one can't recon it completely, but look the same, take a torche light, or take a shot on it with the flash light from the phone, on some angles you will be able to get proper photo, or turn the white to the max, and take off the flipper

Pineapple sponge. I’ve got a bunch of em in my mag cleaner.
