Hi, I recently got my axolotl and set them up in a cycled tank with a filter, minimal water disturbance, hides, correct water parameters, a temp at 67F, and washed pool filter sand. I always treated the water with prime because I live in a city and the water has ammonia in it. They were fine for the first two weeks but then I started to notice them digging into the sand. I believe that caused a nitrite spike because they released gas. Almost immediately the albino began losing gill feathers. I did constant water changes to get the parameters back but they kept losing Gill feathers. I then noticed a fungus beginning to grow which was due to poor parameters I believe so I switched them to a 5 gallon bucket with an air stone so I could keep them cooler in the basement, in the dark, and perform salt baths. I did it and the fungus seemed to disappear but by then all their feathers were gone. Their tails were not curled though. Then they lost their appetite even though I still attempt to feed them daily. I’m now on my third day of ice baths. I’m afraid they might be morphing and I don’t know how to stop it. I change their bucket daily and give them two salt baths each day. Their gills seem to be shrinking and I’m not sure if that’s because there is too much air in the water or something else. Also, the black one seems to be losing its slime coat. They are less than a year old right now. I would really like to keep them fully aquatic, yet despite having correct parameters in their quarantine bucket I feel that the opposite is happening. I also switch their water after they eat (or in this case, don’t eat). I’ve tried feeding them night crawlers, red wigglers, and red worms to no avail. Please help! Before and after pics attached. Thanks in advance!
