My exact experience also!
Any T. can climb glass.
All tarantulas can climb glass just fine, some will slip a bit in premolt when the exoskeleton is worn, but they can and will do it.
Not insist mate... I am having trouble regulating her cage temp though she has developed that spot because my heater went off and it was cold im the room for a bit and i didnt realize it i cant put mor le substrate due to the special stuff i got it radiates heat well for my heat lamp but these temp thermometers i may not really know how to read them.... I live in a very old house with bad insulation.. So trying to make her happy is hard.. Also she gets mad at her crickets she flicks hairs at them too idk why she does that... Do you?
Are you saying it developed the bald spot because of temp.? If so, that’s wrong. They kick hair when irritated by a predator or being bothered by another animal. What is the ‘special stuff’ you speak of? Aphonopelma don’t need any added heat unless it drops to the low 60s as it can get that cold in their natural habitat. If it kicking at a cricket, it means it’s just bothering it and it’s not hungry. Tarantulas can climb the sides of a glass tank, just because yours doesn’t when you’re watching it doesn’t mean it can’t.
Tarantulas are sensitive to vibration, that’s how they perceive the world (detect when prey is around and when predators are as well). Remove the cricket if it isn’t eaten within a short period of time, crickets can bite and harm a T. Never heard of that being used as a substrate, what are the temps in your house? If the sub is jagged and sharp, I’d switch it out to coco fiber btw.
65-70 is fine for Aphonopelma, you don’t need any added heat. Also, I’d advise against listening to ‘pet experts’ as 95% of the ones I’ve talked to have no clue on how to care for a tarantula properly.
1. Crushed ground walnut shells are one of the worst substrates possible. You couldn't make your spider more miserable if you tried. Walnut shell makes it hard for the spider to walk and hunt and she can't burrow in it. Whatever that pet expert was he had absolutely know clue. They only can absorb heat that's there - they won't make anything warmer than it is - and it won't offset the disadvantages.
The problem is the ground walnut shell stuff. If you look closely at the pic you can see how it sticks to the spiders abdomen, but also to the scopulae. It is very light and attaches itself to anything via static electricity and spider scopulae are made to stick to trees and stuff. So the walnut shell dust sticks to the spiders scopulae, inhibits normal walking and makes it impossible for her to climb. It's pure torture for the spider. The dust may also stick to the book lungs and inhibit breathing. See how the spider keeps the abdomen? That's not normal. She's wandering because she's desperately trying to get out.
