You're right he probably is cb.
On the plus side though, I just got the melafix, changed his paper towel (he pooped, which is definitely a plus) and he ate a cricket from last night that I put in. So i'm feeling pretty good about his recovery. He is soaking in the melafix right now!

Note: My other r.e.t.f is completely fine and does not show signs of sickness.thankfully

Here is their terrarium set-up.
