Hi, i'm new to this forum. I own 3 axolotl about 15 cm long. I used to feed them earthworms and bloodworms twice a day. But recently 1 of them (melanoid type) stopped eating, he hide if i put wringgling worm infront of him and when i try to feed him shrimps he ran from it usually shrimps are his favorite food and will snap when i put it infront of his face. Maybe anyone can give suggestion on what should i do. And mostly his hind legs and tail floats and i guess he's struggle to keep it down
