I like the coastal you chose you won't be sorry. I'd highly suggest buying and reading THE COMPLETE CARPET PYTHON By Nick Mutton and Justin Julander.

Providing an enclosure that allows your carpet to climb will be of great viewing benefit. Even the large adult coastal carpets are found 4 meters up into the canopy according to experts that study them in Australia.

I have noticed my boa constrictor is semi arboreal as well and he is fed from his perches about 85% of the time.



I catch my coastal on her perches even more frequently.



You can't go wrong either way and you made a great choice.

I'm strongly considering a SD/Dwarf retic myself. They are also semi arboreal and will climb when given the proper setup.

Your coastal will be a really nice display animal!
