Axolotl vomited, refuses to eat but besides that acts normally

[PedroTrench]

I have an axolotl that's about 4 months old. He didnt eat since saturday, and yesterday he vomited about 3 days worth of food. However, he mostly don't show any signs of stress or other symptoms. His gills are bright red (and they are big and heavy, so it's hard to distinguish if they are curled or not), his color is normal, maybe his tail is curled sometimes, but it may be from positioning. All the water parameters are normal (pH, ammonia, nitrites, temperature, current). I tried feeding him other food (he normally eats fish bits, he loves them) like shrimp, but he quickly loses interest on it. What should I do and what it could be? (I attached him and a pic of his vomit, it looks like fish - I feed him this since I got him in the end of January)

I feed him normal amounts of food and there is no substrate since he is still small.

Axolotls can go for a few days without food so I wouldn't worry too much if it refuses food for a day or so. You can try offering some nightcrawler pieces, small red wrigglers, or bloodworms. Axolotls really shouldn't eat fish too often since they take longer to digest and can carry parasites. Cooked shrimp can make a good treat, but is generally too rich for them to eat frequently. You can also try getting some axolotl or trout pellets, though in my experience my axolotls have preferred and done well on a worm diet. I hope your axie starts feeling better soon and I wish you luck with it.
