Why don't they reach maturity? Are they just not very hardy?They are amphibians that almost never reach adulthood or maturity...most never do in captivity, mine did! I owned an albino one for nearly I believe it was 6 years, during the last 2 it shed its gills and spent most of it's time on a rock half out of water. they are very hard to keep unless you think hand feeding every time on the end of a popcicle stick is easy. I also have him tattooed around my ankel.
