Another dumeril boa vs Columbian boa question

[threezero]

Hey guys. I've recently become a home owner I finally have the snake room I've always wanted. Thus I'm looking to expand my collection and finally get myself the big snake I've always wanted.

What I really am after is a gentle giant. I realize that all snake are individuals, I already have a female coastal carpet that getting a decent size but still hissy nippy at the worst , head butt at her best and flighty as hell. Granted she has calm down quite a bit since I've had her but I realize she won't ever be a "gentle" and I'm ok with that.

With th the calm reputation that boa has I think they are good choice to add to my collection. I dont intent to breed them ever. Would like to focus on my ball breeding project. But I would prefer a female for whatever specie I end up getting because of the general faster growing nature of a female.

Im stuck between a plain old Columbian boa and the beautiful dumeril boa.

From my my research both can be calm placid animals. Columbian boa will get bigger than dumeril boa but their care seems to be the same.

However from rom what I have read dumeril seem to need substrate to burrow in and urate a lot more? I do like to see her as I will eventually have her in a clear front pvc cage. I have hope that this new addition with be the showcase animal in my snake room along with my coastal. I'm concern the beautiful dumeril boa will end up being a pet head (from what I read they either hide or burrow so only their head is shown. Also the concern with feeding problem. I already have a bunch ball pythons that like to randomly waste food, don't really want another problem feeder. Adding to that they seem to prefer colder temperature, because she will be kept in the same room as my balls I'm worry it might get too hot for dumeril and thus cause feeding problem.

With the Columbian. I like their impressive size but seem like the they ain't generally as chill as the dumeril but a better shoulder pet. But from pictures and video online they see to not hide as much and adults are often seen kept on newspaper, my prefer substrate. However I don't care much for the much of the boa morphs, I'm ok with the darker individuals of normal phrase but they ain't that flashy tbh. Most boa morphs are lighter color, I much prefer a darker snake or a snake with more pronounce pattern (albino is my least favourite morph of any snake). Although the Scoria boa look amazing but way out of my price range.

Would much appreciate input from you guys and maybe even owners of both species. Picture of adults would really really help.

also I don't have a source for rabbit and I'm planning to breed my own rats again so whatever I get much stay a rat eater. I'm sure it would be a problem with the dumeril? Not sure about the Colombians. Some feed them jumbo rats some go for rabbits
