So, I was mistaken. I am using erythromycin and fungus cure. I also messed up the dosing schedule and ended up dosing twice as often than I should on the fungus cure. After dosing last night, my wife noticed that the neons had no color. I looked and they were very stressed. They were gasping, and some were laying on their sides in the crystalwort. A quick 50% water change prepped them back up. It would have sucked to lose the tank after spending a day catching them and spending almost as much on medication as I did for the fish.
