Question: What is it that makes axolotls not morph in the wild?

People say less iodine in there habitats or genetics, i dont want to morph my axolotls but i am curious to know what makes the morph into terrestial animals and also from what i read the why
terrestial forms tend to be weak?

Axolotls will morph in the wild in response to adverse conditions, such as a significant drop in water level, water pollution, lack of food etc that would mean remaining aquatic would be difficult.
Assuming that water and food conditions remain suitable axies won't morph.

This is wrong, wild axolotls probably have the same genetic block on metamorphosis as laboratory or pet ones. They may also have other genetic blocks as well. They are dying out due to pollution and habitat degradation and are not morphing and emerging onto land. Water problems kill them not induce metamorphosis.

The genetic block in laboratory axolotls is in the control mechanism which produces a burst of thyroid hormone which then triggers metamorphosis. They morph if treated by thyroid hormone and also iodine treated proteins which have a thyroid hormone mimicing effect bit NOT elemental iodine (which is irritant and poisonous) or iodide.

The response to correct dosage and timing of hormone produces a tiger salamander like meramorphosed mexicanum - http://www.caudata.org/forum/f46-be...eneral-discussion/91260-morphed-axolotls.html

    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?
