Tarantula help

[Chelcie Forrester]

I'm really worried about my male GBB tarantula. I've only had him for maybe around 8 months. He was sold to me as a female but after his last molt I knew he was male because of his bulbous pedipalps and the tibial hooks. At first he was a great eater but now he's been refusing food for quite awhile. I know or at least think (this is my first male tarantula, I've only had females) that male tarantulas tend to start to eat less when they mature and may have smaller abdomens but his is getting small to the point where I am worried. He is obviously not about to molt because his abdomen almost looked shriveled. I put him in a homemade tarantula ICU thinking he was dehydrated. I left him in there for about a day and then returned him to his home but it did nothing. I don't know what else to do, I don't want him to die. Any help or suggestions are appreciated. I posted two pictures but I don't know if you can really see how bad it looks in them.

It a mature male right? They normally don't last very long after they mature. They're not interested in eating, they're interested in finding a mate before their time runs out. Personally I would've just sold him or loaned him out for breeding purposes shortly after he had his ultimate molt.
