Premolt?

As I posted in your othere picture, to me it looks like premolt. HOWEVER, I felt I needed to post on this picture too, because you mention it's falling from the side of the tank, and I see literally no substrate. That's extremely dangerous for a T, especially if it's heavy from overfeeding and/or premolt. A fall like that could easily kill it. You need to get some substrate in there ASAP. Honestly the rock and especially the shell are really dangerous too, but I could ignore those (maybe still not the shell) if there was at least enough substrate for your cutie not to hurt itself. If I were you, I'd get on that before the T either molts or hurts itself. Just some friendly advice

I have 3 in of substrate...coconut eco earth so no worry there. I will remove the rocks and sharp stuff. Thanks for the comment.

That might still be a little low for substrate, but it's a least better than nothing. The general rule of thumb for terrestrials is that you want 1.5 times the size of your tarantula in space after putting in substrate. For example, I have a 2 inch Nhandu chromatus in a Kitter Keeper, and so there's only 3 inches of space between the top of the enclosure and the substrate, and he couldn't be happier. He's made an impressive tunnel system, and he's mellowed out quite a bit since being given the space to dig. I know I might be coming across as pushy, but I just want to make sure you know your options. Ultimately, it's your choice. But I'm very glad to hear you'll be removing that shell!

Is that black thing a cushion? lol

@PidderPeets cool. I think the 10 gallon aquarium is way too big, yeah. At night Cameron's favorite thing to do is to crawl up the side and hang upside down from the tank lid. It baffles me, because what's wrong with the ground?? Yeah I better go and pick up another thing of Eco earth or maybe somehow half the size of the aquarium.

@kevinlowl lol yes kinda. It's a faux leather cushioned zipper case for an item I bought online, similar to a small camera case.

@Winterfr3sh She might be climbing cuz she wants to find a place to burrow. But she could also just be climbing because she wants to. Lol. In either case, it's still better to decrease the chances of her hurting herself. If you're looking to decrease the size of her tank, I do know some pet stores carry 5 gallon tanks. There's also an endless supply of Kritter Keepers to choose from that would be big enough for her, but not too small. They're prettier aesthetically, but they can be expensive. If you're crafty, you could just buy a secure storage container from Walmart or somewhere similar for cheap as dirt. You would just need to poke some holes to increase ventilation. They've got a wide selection of sizes and styles, and tons of people use them to house their various inverts. Think something along the lines of this: https://www.walmart.com/ip/Sterilite-27-Quart-Latch-Box/46001917 . I don't know how big your girl is, but the genreal rule of thumb for tank size is you want something around 2 times her diagonal leg span (DLS) in width, and 3 times her DLS in length. I would go a bit bigger though, since she's looking to molt. Height requirements of the enclosure varies by the type of tarantula (arboreal, terrestrial, fossorial), but I already gave you the substrate information needed for your girl. Good luck with everything, hope all goes well, and hopefully she'll get big and pretty with her next molt

@PidderPeets thanks for the help. I ended up getting a bunch more eco earth and will pile it high in my 10 gallon tank lol which is about a foot tall. I'll put the substrate 9 inches high, leaving only 3 inches from the top to the ground or so. When Cameron gets bigger I'll remove some substrate. Then I'll have extra substrate on hand in case I get another pet...
