BLOOD TEST IS BACK! And not enlightening at all

Plus Blue's poor tail is black after his blood draw. It still had mobility but it's super dark. I searched on the forums and apparently is may or may not get color again

Although if I could just get him healthy I'd be happy.
Despite vet's concerns about renal/kidney issues on xray, blood test shows no issues with either. Only thing is some dehydration. Which is odd because his last poop had a nice white urate, and his mister runs every 2 hrs. I'm guessing that it has to do with his lack of appetite, maybe he is not wanting to drink? Or maybe his tongue? Idk.
Vet is getting in touch with specialists again for their opinion, gonna call back tomorrow. Looks like we might be starting precautionary antibiotics, intramuscular injections

Blue is going to hate this. On phone, it sounded like antibiotic name is Tortaz(sp?)? I didn't think to ask about white blood cell count, vet didn't mention it.
When she calls tomorrow, I'm going to bring vitamin A up one last time. I PMed Mawtyplant for advice on dosage.
Blue is only eating two large feeders each feeding (his appetite is terrible), he stays darker colors, is not as active as he should be. I cut out d3 supplements (only calcium and vitamins for now), increased to UVB 10 and trips outside for natural sun. Now this dehydration thing, but besides feeding silkworms or hornworms... I can't really make him drink. I'm seriously losing my mind over this. I've spent about $400 at the vet now and know nothing
