Does any one know of any research on limb regeneration that has focused on re-regenerating? i.e. -a limb is removed, grows back then is removed again?

This probably doesn't help at all since I don't have sources, but it should be easy to find. A US researcher clipped the digits of a common species of newt, (firebellies or waltls) I believe once a year for their entire lives, to see how age affected regeneration. He did this for so many years he ended up passing the whole experiment onto his son or a younger protege to continue due to his old age.

This was a newspaper article I stumbled upon maybe last year. It shouldn't be too hard to find, sorry for the vagueness, but it's out there.

    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?
