Hitchhiker sponges

[Chefbill]

I've had both of these sponges growing in my tank for well over six months. the yellow I now have two or three spots while the black has spread, about quadruped in size. The black appears completely non photosynthetic as it lives under the archway in my tank.

Anyone else have any interesting sponges that survived?

I have lots of sponges. Great little 'filters' for your aquarium.

I had allot of sponges before I got my Regal Angel.

Can't get pics now, but yea lots. I actually bought an orange one that wilted and died off the rock but is now growing on the other side of the tank.
