I have 2 Sharp Ribbed Newts and an Asian Green Backed Frog....I knew nothing about them 2 years ago when I bought them. My husband had made me a beautiful aquarium out of a recycled 8 gallon glass vase....I needed to put something in it. Now, I'm an avid amphibian fan! Just ordered a 29 gallon tank since they've all gotten so big. Mine have been living in a narrow, deep vase and thrived! We've had a few adventures with them....one became a dust bunny in mid winter when he escaped before I had a proper top. Took hi 2 weeks to recover!
