On AmphibiaWeb they're listed as Least Concern (LC). I do know that they are a Batrachochytrium dendrobatidis (Bd) carrier. For there care they live in rocky outcroppings and crevices near streams in the southwest. I would say a tank that has many rocky ledges, some pieces of drift wood and a small stream like set up would be appropriate. In regards to who has them, breeds them, I'm not sure. Hope this helps somewhat.
