So I have a male Platy that about a week ago I noticed had clamped fins and a little stringy poop. I treated twice with prazioro. He was getting sicker and on one side back near his tail fin I noticed some milky spots but they weren't that pronounced. He was now darting about and swimming upstream in the flow from the hob filter. I treated with kanaplex but no improvement. I set up a 10 gallon hospital tank 3 days ago and treated with jungle fungus cure. He's perked up slightly I guess over the past couple of days but he just lays on the bottom most of the time. The milky spots are still visible and have not gotten any worse. Today I tried a kanaplex-furon2 combo. Tonight he is still just laying on the bottom but will swim in a scared darting manner when I get close to the tank...not a natural swim pattern at all. He does react to food and does pick at it a bit. I feel like I haven't hit on what's wrong with him though as he's not really improving. The community tank I removed him from is healthy and no fish ever got sick. I did test the water parameters and they were normal, 0-0-20. I'm stumped.
