OK, I really need some help here please! I had recently posted about a sick cory cat that I had, and now I think we have sick neons. For a brief overview, my son and I started our tank back in December. It is a 10 gallon planted tank with dirt and gravel substrate. We did a fishless cycle that went wonderfully and then waited almost a week before adding fish. We started with 8 neon tetras, then waited a week before adding 2 pepper corys. We had since added two RCS, a Malina cory, and a Metae cory (which we were told was a panda cory). We added a nerite snail about a month or so ago to help with some brown algae.
The tank has been great. Water has been clear and clean and the fish and plants had been doing wonderfully. I posted last week because our metae cory was acting weird. He wasn't eating and he was not swimming much. After of few days of continued odd behavior (and water testing and a 50% water change) the cory died. I removed him from the tank and did another 50% water change. This morning the tank looked nice and clear again. I fed the fish and was pleased to see that everyone was eating and swimming around. Then, as I watched the fish really closely, I noticed that 2 of the neons have sort of white tints and the edged of their tail fins. At first I thought maybe they just always looked like that and I just didn't notice. However, as I continued watching, I noticed that one of them has a large bubble looking thing on the front of its face by its mouth. Another one has something similar, just not as large. They are still eating, but something is definitely wrong!
I have no idea what to do! I don't want all of the fish to get sick, please help!
