Demobanana Posted January 21, 2022 Share Posted January 21, 2022 Here's some context. Around 3 weeks ago I added a platy in one of my (kinda) new planted tank. And when I say kinda, I mean the tank has been running since last July but I had yet to add any fish in there. Family emergency had me on leave for 3 days. I did a water change a day or 2 before, and I figured if he really got hungry he could've eaten any of the algae I have. I come back, and the platy is pretty motionless with red gills. So I test the water, and everything is good, and the nitrates are around 30ppm, which was about my normal ppm (I had some plants that could benefit off it) and do a water change anyways. So maybe my test was broken, so I took it to the LFS and got it tested, which they said it was fine and offered to exchange it. So I did. After the first couple days I started immediately seeing the same symptoms and water changed every other day. He seemed a little better but still had the red gills. Everything was 0 except nitrates, which were around 10 ppm. Couple days ago I added a small group of pygmy cories. They seem fine as I type this but they also had the red gills the next morning, much like the 2 platys before. Nitrates are still 10 ppm....and there's an HOB and sponge filter getting air in there. And as far as I know, red gills are a sign of parasite, lack of O2, or ammonia burn. But the only thing left are parasites, and I oddon't think they can develop them in less than a day, seeing as they looked fine in the store and the bag. What should I do?
