Dumeri's can be cannibalistic. Also, they have a tendancy...even when not eating, to EAT their bedding! So weird. They don't require more humidity than other boas, unless shedding of course. I have had my boy, and girl (from two different breeders...btw 100 is a good price and 140 is great for two, though they will probably be siblings. That bothers some people, don't know if you mind though) Anyway, had them for six months now...the male has NEVER eaten. He's pooped once, and shed once, and now he just keeps mostly curled up under a coconut husk, only comes out for water and a quick jaunt around the tank. He hasn't really lost any weight. Both of them like their cool side. The female has shed once, and eaten quite a few times, and has grown....though right now she's on strike.
As far as i've read, and can tell...it's just the time of year. They are both still pretty small (though the female is as long as my shoulder to the tips of my fingers, where as the male is barely from my fingers to my elbow). They just want to chill on the cool side. They are always about 72-78 degrees. Only in the beginning did i see the female go onto the warm side.
They have a slow metabolism for a boa. (So do bolivian boas, which i also have.)
I've seen the female sit in her water dish for a day, before her shed. Now that i think about it, i think she's shed twice actually. (I keep meaning to start an excel document on my snakes but i never seem to lol)
They are both very calm, very nice snakes. I actually would have preferred they be a bit more active and more...i dunno...have a bit more personality.
They both burrow. The female loves to burrow and just have her nose sticking out. They are ambush predators.
