I just thought it was kinda cool to see this in my sump area today. I re-scapped the tank and did a water change, I looked inside while I was siphoning the junk off the bottom and saw this in there. It is the largest spong I have in the tank and I can't see it. It is about the size of two half dollars, maybe a bit smaller. I think it is fun when you see stuff you didn't put in the tank. I didn't put a single spong in my tank and I have probly a dozen different kinds/colors. Anyway, just sharing.
