This is my uncle Richard Dick Salmon, Richard for short. We have had him for a little over two years. When we got him from someone else we were told he was 2 years old. So he should be about 4 years old. He has never been a chubby guy, but his body was much fuller. We have been feeding him a mix of bloodworms, brine shrimp, krill, and miso shrimp. We have been feeding him twice a day because he keeps loosing weight. He has looked like the picture above for about two months. He has not lost more weight but he won’t gain weight. We watch him eat and he knows what time breakfast and dinner are. He waits at the food dish and wiggles around till he gets his food. So my question is
How do I get my axolotle to gain weight? Or what might be wrong with him
