Hello,I read an article yesterday regarding the sexing of these newts. It stated that males have a more vivid orange line along the backbone and that the orange coloration was present along the entire limbs. On the female it was usually limited to the tips... Is this true?Looking forward to your comments.Thank you!!!

I would say it were false, where did you read this?
If you look at: http://www.caudata.org/forum/member...-picture13040-neurergus-kaiseri-markings.html you cannot see any real differences between the top female and male's markings. Also a picture of Alan Canns: http://homepage.ntlworld.com/alan.cann/pics/Nkaiseri6.jpg shows no differences as you describe.

Most markings for N.kaiseri seem to have orange along the entire limbs, that would make their a lot of males otherwise, I really dont think it is true.

I too would be dubious about relying on colour to distinguish sexes. When mature, adult kaiseri are quite easy to sex. Males are generally slim and have large, bulbous cloacae, much like any Triturus male. Females on the other hand are generally plumper and have small cloacae which become tubular and prominent during the breeding season.

Hello, I read that on a blog (European one) but having a hard time finding it again, I agree it makes little sense, I just wanted to check here... Thank you for your replies, truly appreciated.

    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?
