LOL, glad i could help you out. I knew it was bugging you. I really haven't ever seen one choke out another. I do remember this sponge being a crazy grower when I had PC lighting though. You will see a wide variety of sponges growing as times goes on. If you decide you have too much for aesthetic reasons you can always place in on the sand to choke it out. All sponges really are good to have though.

Sponge... very beneficial biological filter.

David! Been wondering about you!

Agree, that's a sponge and they are very good at filtering your water.
