Unken Reflex or Posture: A defensive or anti-predatory posture characterized by arching of the salamander’s back, elevated and arched head and tail which displays the animal’s [ventral] surface - often revealing [aposematic coloration] that is normally concealed. To a predator, this sends the message to ‘beware’.
 
I thought I'm gonna share some facts about the origin of this phrase, I think many users haven't heard about it yet.
This phrase was taken from the German "Unkenreflex". The word "Unke" means "firebelly toad" (Bombina spp.), which name imitates their sound ("unk-unk-unk"), and they were the first amphibians where this defensive behaviour was observed at.
(note: the Hungarian name of firebelly toads - "unka" - is originated from German too)

    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?
