Vomiting Axolotl

Earlier tonight my new axolotl started vomiting and I’m not sure what to do about it. He hasn’t eaten for about 24 hours and the last thing he ate were bloodworms (which is what he vomited up), he first vomited about 10 minutes ago and then started doing what looked like dry heaving for another minute or two, he’s not doing it anymore as far as I can tell but I’d like to figure out what caused it so I can keep it from happening again. He’s on sand and I use a feeding jar so I don’t think he’s impacted and the temperature usually stays below 68 F. I’ve had him for a little over a month now and haven’t had any trouble with him so far. He’s always been a pretty healthy eater and aside from vomiting I can’t see anything physically wrong with him.

I feel so bad for the poor little guy so any help and advice would be greatly appreciated!

Do you know your water parameters? 24 hours isn't a long time for an Axolotl to go without eating. I would feed it again and see what happens, this might have been a 1 time thing.

The ammonia is 0 and the PH is 7.4, I don't have a kit to do the rest of the readings but I'll get those checked today. I know 24 hours isn't long to go without food, I was just saying that that was how long it was between him eating and then vomiting the food back up because I wasn't sure if that would be relevant or not to figuring out what was wrong

He's been acting pretty normal since then, could the problem have been that I accidentally left the tank light on all day yesterday? I usually keep it off all day except for a few hours because I heard the bright light can stress them out, is that true?

Sometimes they'll throw up if they're too cold, or if they've eaten too much, even hours or days later. My female once barfed up a weeks worth of waxworms and half-digested nightcrawlers.

Lights can stress them, but it probably wouldn't lead to him vomiting unless it was super-bright.

I'm thinking overfeeding may have been the problem, I usually have leftover bloodworms that I give to my fish and I didn't have any yesterday and he only threw up part of what he ate, not all of it. I'm still going to check the water to make sure everything else is alright, but thank you guys so much for your help
