Can someone tell me what this is please?

The bubble thing to the left of my torch. Just noticed it and I dont have anything else like that in the tank. I removed it with a pipette and it was a hollow orb-type thing. It was hard and kept its shape. Any ideas? Thanks.

Get it out of there if you can. It can spread and is tough to fight once it has a foothold.

Agreed with all above. If you can’t manual get rid of them, emerald crabs should take care of them.
