Brachypelma albopilosum (age ~20 months)

Male 100%

Yep, male.

Thank you.
Unfortunately, that means three out of three of the slings I bought in 2015 were males.

@EricSJCA That sucks, how big were the slings?

@Ghost56 Very small, like 1/4" (6mm) with legs curled up. They were only $20 for all 3 at a show. I was assuming we had a 75% to get a mating pair until I learned that the males would probably die before a female matured. These were my first tarantulas since I caught one locally as a kid.
Oh well, they've been interesting enough so far, and I got well over our $20 worth of enjoyment out of them.
I have three Grammostola pulchripes slings all ready to take their place when these males pass on.
And I have two P. metallicas growing fast right now. I'm hoping arboreals won't outgrow their cages before I get a chance to look at enclosures at a show in May.
