What have I got here

This is in the back of my AIO. They are popping up here and there in the tank now. Please tell me this creature isn’t a huge problem. About the size and color of a grain of rice.

Pinapple sponge. Harmless filter feeder and a sign of a healthy reef. It was the first mass growth i had in my new tank when first starting out in the hobby.
