I was doing a water change today and noticed a two greayish white "balls" in mt tank about 4 inches apart from eachother. They are small (about 1 - 1.5 inches in diamter) and have white fuzz on them that kinda looks like mold? What is it?
I currently have 6 neons and 1 catfish in the tank.. HeLP!
They are laying next to a peice of driftwood and some plants kind of in the shade..
This is a 55gal tank..
