What is this and how do i treat it? I have 2 black neon tetras right now and tried to add two more last week but the two new ones seemed to be sick from the LFS (guess i should pay more attention when im buying). I noticed the next morning one of the new ones had a fluffy white substance on it and both the new tetras died that day. The original tetras are still alive however its been almost a week since the other tetras died and now i noticed i have that fluffy stuff growing on a piece of driftwood i have in the tank. What is it and how do i get rid of it?
Thanks
