An unlucky start bud, but it does sound like it was shipped to you whilst in pre-moult, bad as means it would have become a bit dehydrated before it tried to moult. Don't give up though, it'll get better.
Trust me bud, there are folks out there who make bigger mistakes.... One of our Ts we got from a couple who had melted a hole in the bottom of it's plastic tank with a heat mat, and they hadn't even noticed....Didn't even need a heat mat. lol
Keeping Tarantulas can at times prove to be quite a solitary endeavour, seeing as most people tend to recoil in horror when they are informed about the hobby you hold so dear.
And so we here at Tarantulas UK aim to provide a friendly and welcoming forum for hobbyists of all experience levels who may wish to discuss or seek specific advice relating to keeping Tarantulas and maybe make a few friends at the same time!
Thanks for stopping by at Tarantulas UK and we hope you stick around.
