Has anyone ever had any, and got any advice on keeping them ?. ive just got a couple as ive always found them interesting, i know the basics, and have read up on them on the net. very strange looking things, there actually a salamander, and can under some circumstances, undergo metamorphosis from neotenic into terrestrial form if you slowly lower the water level so they can get out of the water, then the gills can close up, altough this quite rare and will shorten its life span, and i dont plan on doing this anyway, just find it interesting.
