Not a fungus or a mold, but thanks guys
It may just be the pic. I thought sponges were more "solid" in construction. Thanks for sharing.

Looks like sponge to me, very cool to have found some that will grow in an aquarium, most of the time they starve. I get bryozoans where I live, they are cool, colonies big as basket balls sometimes, snails eat them like candy. There is a species of sponge that is green, it grows symbiotic algae in it's tissues, very nice to keep. Don't let all the "scrub and boil" people bother you, that what they used to do in salt water too now they pay big bucks for live rock with all the "critters' left alive. I do the same thing with bogwood, lots of neat stuff comes off that wood. Most harmful parasites have complex life cycles that cannot complete their lives in a closed system. If you feed lots of live daphnia you can get colonies of hydra, very cool and some of them are green and live off internal algae as well.
Are you referring to the green stringy stuff? A better picture would help us all. Didn't even know they had freshwater sponges till now. I've learned something new today!
