My son was helping me clean a danube cn tank. There are sixteen fully matured newts, and he noticed one of the newts has six toes on one of the back legs. It has a full crest and is otherwise identical to its tank mates. Has anyone experienced this with their newts?
 
I expect by now the population of T.dobrogicus in the US must be getting rather inbred so this kind of thing is likely to pop up more frequently...
Polydactyly is not unheard of in caudates, of course, both congenital and acquired after a faulty regeneration (although you can typically tell the two apart), but it's rare.
 
Anomalies like this show up in nature and in captivity. It is a curiosity but most likely does not indicate any big problem with the salamander.

    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?
