They are a cool spider! Malaysian Earth Tigers, Cyriopagopus thorelli have that typical spicey asian attitude. They are a large species and can be very fast when they wanna be.
Built like an arboreal tarantula, they are more opportunistic in choosing a den site. Though mine choose to live a terrestrial lifestyle, Mark Pennell, last year, embarked on the Malaysian Earth Tiger Tour, and reported that this species was found in trees. They can be found in trees, in the ground and everywhere in between.
This species is one of the few that are sexually dimorphic even before males reach their ultimate molts. Females are much darker overall, and males are obviously greener.
One asian specialist, Volker von Wirth, suggests that pet-trade Cyriopagopus thorelli are actually Cyriopagopus schioedtei.
Pictured is an adult female.
And here is an ultimate male. You can obviously see the big difference in color change. Matured males are a very neat tarantula. As I've said before, I wish they could last forever at this stage. One would notice, that males, in this stage are extremely defensive.
So do you keep yours as arboreal or like a usmabara and give them the choice with a couple inches of substrate and a tank turned upright? By the way after seeing those pics I definetly got to get one. Anything else I should know?
John is right about this species being found everywhere, I talked with Rick West about this species before I purchased mine. He said they were opportunistic burrowing/arboreal spiders. Living anywhere from the crooks of trees to under rocks, in burrows and anywhere in between.
