I just started up an old 10 gallon tank because my Molly is prego and I wanted to keep a nursery tank ready once the fry drops... I added older plants and decorations from my current tank to get the tank cycled faster. However I added couple of rocks and I noticed some white soft stuff growing on my rock... I'm wondering of this is some kind of a sponge...? I need some help confirming this and if not is it harmful? Thanks guys!
