Deloustali juveniles

A year old and 6cm long specimens. They live on chopped earth worms.

But...they will not get nice orange bellies this way. You can see that as larvaes they didn't have any Daphnia's else they would have been more orange.
But that's just a slight remark, they look very healthy, and that's much more important!

serge,
what is a good land food that can help with orange bellies?

Maybe they will some time

.
Except earth worms I put small amounts of tiny crickets and woodlice (porcellio). But... do insects and terrestrial crustaceans contain more carotene than earth worms ?

One can dust the feeders with tiny amounts of carotenoids to enhance coloration.

i guess one could gut load the feeders too (a lot easier than teaching a newt to eat carrots!), but i was wondering -if in nature they are on land at this size, what natural food do they consume to add to the colour-or is it assumed that the colour is from food they consumed during a crucial period as larvae?

lovely animals, i think yellow is a refreshing change from the usual orange/red firebelly. I'd keep some like that unless it is essential for them to have carotenes.

Juraj, very nice!!! You must be one of the first people to breed this species in captivity.

Paris, I've been dusting fruit flies lately with Nekton-Rep-Color. It's a reptile vitamin/mineral supplement with carotenoids. It could also be used on crickets, woodlice, etc. In the US, they sell it at blackjungle.com and nyworms.com.

The first was Czechoslovak scientist Ivan Rehák, in 1979 or so. He has been keeping and breeding them successfully till today, I think.
Rehák, I. (1981): First reproduction of vietnamese newt (Paramesotriton deloustali) in captivity. Živa 29 (6): 231.
Only in Czech language...

And second article from the same author:
Rehák, I. (2002): Vietnamese newt - dying jewel from Tam Dao. Živa 50 (5): 223.
Again only in Czech...

Hi,

I am always a bit suspicious about adding artificial xanthin derivatives (for enhancing reddish colours) to the food. At least in birds, this can lead to severe liver problems. In my newt offspring, I either use Daphnia during rearing or I just try to manage to have yellow bellied animals...

Juraj,
who did breed them?

    with axolotls would I basically have to keep buying and buying new axolotls to prevent inbred breeding which costs a lot of money??

    Not necessarily but if you’re wanting to continue to grow your breeding capacity then yes. Breeding axolotls isn’t a cheap hobby nor is it a get rich quick scheme. It costs a lot of money and time and deditcation

    Would Chinese fire belly newts be more or less inclined towards an aquatic eft set up versus Japanese . I'm raising them and have abandoned the terrarium at about 5 months old and switched to the aquatic setups you describe. I'm wondering if I could do this as soon as they morph?
