Iíve searched and searched and nothing seems to fit with what we are experiencing. We have a 30g tank with 6 glo fish. They were in a 75 gal
but our filtration system died and instead of purchasing new we chose to bring an older 30g out of storage. We put in 25% of the old tanks water since it was in good shape and added the rest fresh RO
water. I ran the new filter and added decor for a few days then transferred the fish. A week later and we have these pink fuzzy balls all over the bottom of the tank as well as some clearish slimy fungus type stuff in blobs in a few locations. I took a few of the balls out and they dry pink and hard. About the size of a pea. Iíve tried removing as much as I can and have been doing 25% water changes the last two days. Our fish are being affected by whatever it is going on - we lost 2 today and the remaining are mostly uninterested in food and spend much of their time at the top of the tank. Iíve never seen these balls/slime before. (Tested with strips today, all levels look good. We have an air stone going and fluval30 filter on high) Please help this clueless mama out, our local fish shops are chains and the kids donít know what these things are either.
