Brachypelma albopilosum, Male Or Female?

What kind of lighting are you using? Is it for viewing only or do you have it on all the time? It looks really neat! As for gender, it looks male IMO but I am far from an expert

Male

I took it with a flash, but the LED over the screen is a red-blue grow light for a plant in the tank.
It was a mistake because it is good exclusive light for viewing, in my opinion, though it's not bad as ambient light if there's a stronger white light nearby.

I was afraid it was male. That was the verdict in a previous molt picture also.
The strange thing about this one, is that it's much bigger than its siblings and still doesn't have any tibial hooks that I can see. The others' had obvious hooks. It also doesn't climb the walls at all like the others, but rather spent the whole year sealed in its 'cave' and is just now starting to hang out more and reaching for food outside its hole. I'm surprised it grew or even survived because I couldn't tell if it was eating down there.

You might find this interesting: I also had two of its male siblings on the same shelving unit that matured at different rates. The top shelf matured first, the middle shelf matured second, and this one matured almost a year later (if it's even mature). Though that's only interesting if it's a male. Since this one is only an inch off the floor in my upstair bedroom, its enclosure obviously keeps the coolest, while the top one was probably the warmest, even if only by a degree or two.

Specimens usually differ. Some male Brachys mature 5+ inches. Some will be monsters

Since there are no tibial hooks yet, I assume there's another molt coming. It's already much larger than a now deceased and also a barely living sibling; so this is going to be a huge male.

Good news: The earliest matured got to mate with a female in Arizona before it passed away.

Yup. Its not mature quite yet. It will be large
