Hi, I am new to axolotls and need some advice. We have only had him a short time, a couple of months. The tank was not set up and cycled before we got him. I contacted local pet shop and asked how to care for him and as you can imagine got bad advice! Was told that gravel was fine, feed him pellets or uncooked shrimp/prawn. I had some water issues and was told to put live plants in. Initially he wouldn't eat but eventually got him to eat bits of prawn and thought I was getting on top of things, he was eating well, growing, and I was doing regular partial water changes. Then plants started to die? Water parameters deteriorated, I did more research online, removed plants and gravel and am doing regular partial water changes as he stopped eating. I am using Seachem Prime to treat water. I tried him with earthworms, not interested. The ammonia went sky high, I am using API liquid test, I mean 8ppm!!!!!!! I did a major water change, 90%, I really didn't think I had a choice. I thought about fridging him but have no experience! It has been a week since he ate. He is around 6-7". Tank is small, 25litres, 40cm long x 30cm wide and I am going to get a larger one, it has a filter with sponge and spray bar, he has a tunnel and airstone. So today I noticed he has a"blister" on the side of his face and some skin peeling from his foot. He has not pooped. It is possible he has swallowed gravel although I always hand fed him. Just checked water. PH 6 Ammonia 1ppm Nitrites 2 Nitrates 5ppm I am on tank/rainwater. PH from tap is 6.5.
