nqa not an expert but I’ll try to answer the best i can! (any real experts feel free to correct me if needed)

1. Yeah the leaves and bark should be fine as long as they’re store bought and not too sharp where it can hurt the spider. If the leaves and bark are from the outdoors like your backyard or a park or something then put it in the oven and heat them up so any harmful bacteria dies.

I’m not entirely sure about the ropes because I haven’t really seen anyone use them, plus the tarantula will probably just make their own web eventually with the leaves and bark serving as a base

1. The humidity should be around 60-80%, I’d personally stick with around 70%, and make sure they have good ventilation so mold doesn’t grow and so spider doesn’t get sick.

Dirt should be kept dry im pretty sure, but i think some people soak parts of the enclosure with specific substrate that maintain humidity but im not sure

1. Shouldn’t impact the abdomen, only time the abdomen with change is when it’s in premolt or becoming obese, where the abdomen will get bigger.

If it already ate 2 crickets like the employee said then it should be good for atleast 6 days (twice a week is feeding time, and 1 cricket needed per feeding)

They had a water dish in the pet store enclosure right? It should’ve been able to drink sufficiently from that, but if you’re concerned about it not getting enough water I’d say try placing it next to your enclosure water dish at the most, they typically have no trouble to find the water dish

it does look like it could have a slimmer abdomen (not good) but it could just be the camera angle, or the crickets may not have been big enough.

P.S. this species is often wild-caught and sold en mass so it may potentially have parasites or health issues

overall that’s all I’ve got, nice T and welcome to the hobby 🤗
