It's a terrible day today!
Two hynobiidaes died in the same day.
They were all raised by me from eggs.
I cann't understand why they died so suddenly.
The room temp is 15℃.
I didn't stop feedding,was that reason?Because i found half-diggested earth worm spitting from one's mouth.
There were much excrement in both large intestine(normal?) .
And i found many black dots on both large intestine wall(normal?)
Here are pictures,mybe you can find slues for me.
Thanks so much.

Hi zhanggeer,
Did you feed the same worms to any other animals besides these two? I am not sure about the liver spots, hopefully someone more knowledgeable can comment on this.

How long after they died were these pictures taken? They look bloated.

no sign of worm or any infection caused be worms or one cell organisms or viruses, also skin without any sign of infection with fungus or bacteria, liver seems normal, no yellow/brown colour or spots seen with bare eye, but maybe under binocular!?
possibly the black spots on the wall of intestines are some kind of worm infestation.
I send pics to my friend who is a vet, he can see possibly something strange.

check water quality and food quality.
Maybe your worms came from a polluted source and the newts got poisoned!?

my vet says that the black spots at the wall of intestine are pigments (the big dark red mass inside intestine is just digested food).
he can not see any sign of infection or poisoning at liver or intestine, he says everything looks very normal and that you did a good job opening the belly for photo ;)

so the reason of death remains myterious

    they get fat after eating their worm pieces and it takes a long time to look as thin as they do in wild life pictures. there are no other prey items available around here.

    So, how often do I have to change the soil in my yellow spotteds terrarium? The soil looks fine, he stays under his rock all the time, so should I maybe only change put the soil from udner the rock? Or do I change it all out cuz its all stayed moist and I dont wnat it it mold kinda deal? Its been around 40 days with the same soil. It looks and smells completely fine though. I dont know what salamander poop even looks like, but Im not even finding any. I put pill bugs in his cage for him and they disappear, theyre not burrowing, so he MUST be eating them. What am I looking out for when the soil needs to be changed? Clearly the people whos aid they were coming to seize my salamander have forgotten and arent coming back.
