Hi!
This one really looks very thin, specially the tail.
If you decide to get them, give them a lot of hiding places, high humidity (spray a lot + live plants) and keep them between 18 and 24, 25 C max.
And I would keep every animal separately, because they could be aggressive.
More stress is the last thing they need.
And just recently I found out that they like to eat snails as well (at least females), like Uroplatus. It makes sense since they live in humid areas, where snails are usually found.
I'll post some photos of my adult animals and my terrariums shortly.
