Help ID fast growing red thing(sponge)?

Anybody able to help me ID this or decide if it’s an issue?
showed up about 3 weeks ago and has been growing rapidly over any surface ( rocks, macro algae, upwards)
I haven’t touched it yet

thank you

HOW MUCH DOES A FISH’S FEEDING REQUIREMENTS AFFECT YOUR STOCKING DECISIONS?

A lot! - I avoid fish that require frequent or specialized feeding

Quite a bit, but an automatic feeder can change my answer

It depends on whether my nutrient export can handle it

It depends on how badly I want the fish

Not much. I’m willing to adjust my routine

Not at all. Feeding demands don’t limit my stocking choices

I usually learn about the demanding feeding schedule after buying the fish!

I haven’t really considered this before

Something else (see my comments in the thread)
