All you lucky west coast people the dream species for me, especially the terrestrial version. Do the more southern populations have a higher percent of terrestrial animals or is your area just unsuitable for aquatic adults?
I am planning on building a replica biotope of the stream near adjacent to my house that I've found neotenic D. tenebrosus in. Once that's all setup and running with a chiller I'll probably raise a few out and work from there.
Oregon will be implementing new rules in March that allow for the propagation of wild caught non threatened non game animals with a permit. I'll be applying for a couple of them for different species.
