I have several N. s. strauchii that are offspring of spring 2003 imported as CB from Europe. At this point, they are subadults.
I am doing a bit of an "experiment" regarding care. Half were put in an aquatic setup this winter, and half are still being kept terrestrial. I didn't want to put all of them in water, as some people have had them die when put into aquatic setups. My water here is very hard and alkaline (pH close to 8).
Interestingly, the terrestrial ones appear to eat much less, but continue to grow at about the same rate as the aquatic ones. The two groups have somewhat different food preferences and diet. If anyone is interested, I'll post more details. I haven't measured them lately to see if the two groups have any differences in growth rate, but I could do that too.
