Mike-Good luck with your babies. Ian, I'm sure, has been a great help!
Lims-I've got some baby hong kong pics up at the moment in the paramesotriton section of the forum, I'll take some new adult shots, just for you!
JWerner-I haven't found them boring at all, they have very definite personalities!
