My son has had 2 for about 5 yrs now, very easy to look after, we dont feed raw meat too messy, Axolotl pellets 2-3 time a week. In winter once a week. They also eat worms, slugs and small fish, we get cockabillies from the lake.
One had his leg biten off but grew back, another had to go to the vet because it had a big stone stuck in its mouth ($32.50 later)
Very easy to keep. My son cleans the tank once a month.
