I have been keeping N kaiseri and N strauchii since Feb 2010. I have kept both groups aquatic the entire time. Both have areas to get out of the water, but rarely do. I have caught them at times late at night out of the water. I have produced N strauchii for 3 years now and have had N kaiseri eggs for 3 years as well. I did not have a male kaiseri until late last year. So I anticipate getting fertile eggs from them next year. I have not lost a single animal. Additionally, I have kept back strauchii from my offspring and to date, I have not had a single morphed animal die on me!!! I have lost larvae and have had some cannibalism from time to time. I see it the most just before morphing. They seem to get more aggessive and eat a TON!!!
