Red Sponge Hitchhiker

[OPL]

Has anybody ever seen or know what this is? It was attached to the bottom/rock of a Cynarina coral which has been dipped twice in Coral RX Pro.

Dip didn’t shift it but it came off pretty easily with a small pick, only other critter found was a bristleworm that’s since been dealt with.

Thanks in advance

Looks like a sponge of some sort. Harmless filter feeder

Not sure why you removed either the sponge or bristleworm since they are both beneficial to your system.

I didn’t know what the sponge was so I got rid on the basis of its better to be safe than sorry.

I don’t mind bristleworms, already got a couple in the tank (that I know of). It had gone through 2 rounds of dipping so it was probably dead already so got rid aswell.
