@KezyGLA I'm not sure that I agree. B. schroederi have a very light colored carapax as slings/juveniles and they are among the faster growing Brachys. I'd say there's about a dozen or so Brachys and Aphonos that look like that at sling/small juvenile stage.
@boina yeah pretty slow growing and when she molted like months ago she was darker with some kind of blueish shine, well tnx for help gonna leave it another half a year or year probably before anyone can be sure
@Dovey well doesn't look to me as grammostola, but by the growth rate It kinda crossed my mind, tho to be honest I kinda think it's a Aphonopelma caniceps or something like that, hopefully will be able to ID after the moult, also it is not docile as grammostolas i had, it's pretty calm and slow but can be pretty defensive, sometimes can't even touch her back legs when doing maintenance, yet again it's every T for it self
