Hello,
I cant seem to find what this guy is, Anybody know?
The big red thing on the left - Its rubbery. Showed up one day about the size of a penny.
I let it grow and now its about the size of a dollar bill. I cant find anything online that looks like it.

Looks like it could be 2 things it’s either red plating coralline algae or red sponge.
