Defensive, not aggressive. But you pretty much got what I was trying to say.Im not calling you stupid or anything but most if not ALL females cost more because people want to breed them, and they live longer, common T knowledge. I got my first T in December and i know this. Do a lot of reading on ALL DIFFERENT KINDS of Ts. Cobalt Blues are aggressive and if your a beginner you really shouldn't get one. Unless you cant live without one. Try a Avic Avic, B. Smithi, G Pulchripes All every beautiful Ts you can handle without problems.
I haven't seen my H. hainanum since I got it so you would be correct there.If I'm not mistaken, as I only owned an H Lividium for a short time(rescued from pet store, but it didn't survive long), that they also spend most of their time in burrows so you wont get to see it much
