How often are you feeding him and how long did he go without eating?
(I'm at work, the internet connection is SLOW, and I do not have a
chance to go back and read old posts, sorry)
when my veileds would go on hunger strikes for a few days, it was
always the same problem, one I would not repeat. I over fed them.
I gave them too much food in a short period of time, and after a week
or two of this, they'd stop eating for several days, usually only
regaining interest when I gave them something new, like a superworm
pupae, cicada or grasshopper.
I was young, and didn't know any better. I thought that they'd stop
eating when they were ready...
so, I fed them all they could eat.
My WC male veiled, only 12 inches total length, would eat over 20
adult crickets a day, for several days in a row. It's no wonder he
would slow down! My big male, twice his size, eats nowhere near as
many at once.
Try silkworms, and silkmoths, superworm pupae and beetles*,
mealworm beetles and pupae, and waxmoths. Vary it up as much as
possible, using the less stable adult forms of classic feeder insects for
added variety. Most of the time, the adults will be less nutritious than
their fat larvae, but it'll add variety. Also, the adult beetles are very
crunchy, even more so than the larvae. Some crunchieness is good,
but not too much. I try to balance it out.
Superworm beetles are nice an dbig and crunchy, most chameleons go
nuts for big crunchy beetles. The onyly problem is that they secrete a
natural chemical defense from their rear end - I bever had a veiled that
would eat them. They'd spit them out as fast as they brought them in.
My melleri was gettign fussy, and wouldnt' eat superworms last year. I
took a beetle, rinsed it's rear end off well, and he loved it. He eats
them all the time now, as a treat. By far his favorite food item, more
so than even large roaches. I have yet to try washing them and feeding
them to veileds. I'm tryign to start a superworm colony, so I dont'
want to waste the adults right now...
