I do not suggest G. rosea. I, personally, do not like them at all.
I suggest Chaco's (G. pulchripes) and adorable little pink toe's (Avic. and what ever kind you want. They're all awesome. A. versicolor's are stunning.).
Don't buy a certain kind just because we suggest it. Go to shows, check em out, talk to the breeders. Ask their opinion. Ask what their calmest and nicest one is. They're all different. Shoot, I've owned pokies that were as calm and friendly as can be. And I've owned rosie's that I swear wanted me dead. Haha.
