What is this purple thing!!

This organism came in at the base of an acro coral and has grown in a mat to be a couple inches in diameter. Awesome color and is literally like a piece of rubber with ridges. Actually developed a couple of bubbles in it that burst, left holes and repaired themselves

Very intrigued as to what it is!

Cyanobacteria. Maybe a sponge but odds are cyano.

If it is rubbery it could be Collospongia auris

That's awesome. Took a look online and looks like the Collospongia!! Anything I should be concerned about

Does anyone know if you are able to frag this sponge and if in doing so you run the risk of toxins?
