That's very impressive. What kind of sponge is it and did you do anything to care for it?

Collospongia auris ! I think lol ! And nothing special it just seems to thrive ! My tank is full of softies so I just dose iodine (but this always brings up a debate)

I doubt you need the iodine. I have lots of softies as well and bought a Hanna iodine checker (don't dose what you can't test for) and was surprised how high it was. Stopped dosing and never saw a change in the corals.

There is evidence that those sponges are symbiotic with certain types of cyano. They are also known to grow quite large in home aquariums.
