Sorry for ask a very basicly question,I'm new with newt and sal.
I sometime found some Larvae of Ambystoma for sale in my country[Thailand] but nobody known which species of them and someone bought and kept them all life in aquatic,that make everybody believed they are all A.mexicanum,but somebody tried to decrease water level and some larvae transform to adult A.triginum.
So,Pls suggest me to know how to separate Ambystoma larvae?
as the one in pic dealer told, this Axololt kept all in full aquatic.but he did not know its species.

Those are axolotls.

Some adult axolotls will spontaneously go through metamorphosis if the conditions are met. It's rare but it happens.
 
The second one is an axolotl, 100% sure. The first one could be a tiger salamander larva or an axolotl. If the seller is an idiot, they could have mixed the two species together. If more than one or two went into metamorphosis, I would suspect some of them may have been tiger sals. Do you have any photos of the animals after metamorphosis?
 
I got these pics from dealer's site,and most of them sold as Axolotl not tiger sals's larvar,All larvae always for sale as Axolotl. so I would like to know,how to separate each species in Ambystoma.
 
It would be rather difficult when they're larvae, especially A. mexicanum and A. tigrinum/mavortium. The tiger salamander larvae tend to have squatter 'sausage' shaped toes, where axolotl toes tend to be longer and slender.

    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?
