I wonder if it's really G. graphurus; I don't know enough to know, but I just read they're highly polymorphic, so it seems like as a retailer you could call it that and no one would really attack you for it. Either way, a beautiful animal.
What precautions do you have in place, if any, to prevent it from smashing the tank? I've read horror stories of water and shrimp all over the floor.
Ive in saltwater a good while and honestly the tank smashing thing can happen but is really overblown and a large species would be needed to do that. My glass is pretty thick and they just dont do it as often as people wanna make it out to be. Kinda how alot of things about tarantulas get over exaggerated.
Ive had Jables about a year and he is a pretty calm guy.
He is also on the smaller/medium end of Smasher species of mantis at 3.5" or so.
