Sadly, I no longer keep any boiga sp. Lost them when I went to prison....
I did keep mated pairs of three subspecies of Boiga dendrophila (dendrophila, divergens, and melanota) and B. tanahjampeana.
I'll get some more when I can afford to. They can be expensive, here in America, and I insist on good cages for my animals.
They're great snakes -perfect for arboreal displays- although some will only feed at night.
BTW, don't handle them at night. They can be a little grouchy. (I probably should have mentioned that. )
