Almost all of my indoor carnivores live in a tropical terrarium in my reptile room. The only exception is my N. alata, who is a lot more tolerant of general household conditions (fluctuating temps and humidity) than my other carnivores.
The terrarium. Husband made the custom hood for it, with lights on timers, and a computer fan to circulate the air. It stays toasty and humid in there.
N. bicalcarata (I have 2 of these, one Brunei orange, and one Sarawak Giant) Both are still small.
D. intermiedia. Hardy, likely cuban or other tropical. Sets seeds and I get volunteer sprouts regularly.
D. capensis, with visiting, N bicalcarata.
