This is growing just below my Green Star Polyp. It is getting bigger and knowing my luck it is really bad. Any help would be great. Thanks

If it's Tom's tank, it's probably is a bad sponge.:xd:

I knew that some sponges could wage chemical warfare but I figured some carbon would take care of it.

Promising research is being done on sponges being used to cure diseases.
