Not eating, losing weight

[Fangz]

My Avic. hasn't eaten in months and he's losing weight. Lately he's getting lethargic and actually going to the bottom of the enclosure. He's on the bottom right now.
He was drinking OK for most of that time, but, I haven't seen him drink in the last couple of weeks, but, I have been leaving him alone as much as possible so as not to stess him.
He last molted a few months ago, I think he's eaten a couple of times since then (but, not in the last two months, maybe a little longer), but, wasn't too enthusiastic about it even then.
He was very active for awhile right after the last molt.
I've had him almost a year, he was about half grown when I got him.
I think he may have tibial hooks, but I can't see very clearly and I hate to bother him when he's obviously not feeling well.
Would this be normal behavior if it was his ultimate molt (I can't find any information concerning this specifically).

If it was his ultimate molt what do I do? Do I just leave him alone? Should I still offer him food?
How can I make it easier for him?

Thank you in advance for any help.

If he is an ultimate males its very likely he is on his way out. Still offer food but don't leave it in for very long. They only thing I can imagine that will be worse when you find he has passed is finding him like that being eaten by crickets

is it a mature male? if so, his life may be nearing an end. if so, sorry about that. nothing you can do but try to feed him and water him until he gives out. best wishes.

Thank you both for the replies.
He was in a front corner this morning and I was able to get a better look at him, his pedipalps are definitely bulbous, so I'm afraid his days are numbered.
I'll continue to offer him food (I'll keep an eye on it and won't leave it in long).
You're right it would be horrible to find him being eaten. My bigget fear is he would get so weak he wouldnt be able to get away and would still be alive.

try breeding him with a mature female thats smaller than him, if at all possible to give him a better chance
