has anybody attempted to grow freshwater sponge in thier aquarium. the Spongilla (genus?) is the only thing ive found so far. sponges sound quite benificial to the tank. I wonder if you could actually replace mechanical filtration with a living sponge in smaller tanks. hmm. the only pics i've found make it look kinda ugly though.
I am going to try to find some more info on this.
