Mixing Notophthalmus subspecies?

[geron]

I was wondering if Notophthalmus viridescens viridescens and Notophthalmus viridescens dorsalis have been kept together? I assume they haven't because of messing up the gene pool or different temperature needs. I just needed to know because of this qoute right here.

"Four regional varieties (or races) of the eastern newt exist. Studies of DNA indicate that these varieties are not true subspecies, as there is very little genetic divergence among them."

They can interbreed so bad idea...
Even if they are not considered subspecies they are definitely distinctive and that´s enough to be careful, keep them separate and not mix them willy nilly.

Not to dig up old threads, but it is like keeping different color morphs of dart frogs together. They are not separate subspecies, but should be kept separate from each other due to mixing

Well I'll join you in your thread mining operation and say its like keeping different races of C. pyrrhogaster together, although as far as I know they could be given subspecies, or even full species status in the future.
I have read articles and accounts from when pyrrhos were common in petstores of pairs that flatly refused to breed, with hindsight I would guess this was because they unknowingly had animals of different races, but that's not to say all different races are unable to hybridise though...
