Dumerils Boas are NOT terrestrial

[Dutti]

Lol ok so

I swim sometimes for fun. That makes me an aquatic species, am I right?

Young dumeril's do climb sometimes- that's known. Just like MANY young terrestrial species. Once your dum gets older and bigger, they stop climbing altogether. I've removed my branch from my dum's enclosure once she was around 3 years old, because she just burrows under it and never uses it.

And regarding your setup- Where are the hides? Where is your thick substrate? Dumeril's need hiding places and they are a BURROWING species, not even just a terrestrial species. If you provide them with substrate at least 3" thick, they'll burrow way under and have their nose poking out.

Your substrate is so thin, and your setup is so open, there is no doubt all it is doing is attempting to seek somewhere more secure.

His substrate is Aspin and is thick enough for him to burrow himself deep which he does. He has a hide which he uses very often but its not shown in the photo. The photo does not show the whole enclosure. So he is not climbing to feel secure as you have suggested. I don,t think that he will stop climbing as he gets older
