I'm trying to make sure seller wasn't wrong and it actually is an Aphonopelma bicoloratum and not B. boehmei. It's still pretty small, about 5cm long, molted about week ago.
Phone camera zoom allowed me to suspect it's also a female.
My A. bicoloratum decided to molt while I was sleeping. I can't wait to see how much bigger it's gotten. Maybe I'll be able to sex it after I get the excuviae.
Also, is there any way to make sure it's A. bicoloratum and not B. boehmei? I don't know if the seller can be trusted.
