So I have tried just about every worm possible for my guy to eat pheonix butter wax king horn silk (no meal worms) and He wontxeat them unless I force him to eat them horn worms being the last of which I have tried.
Not to mention getting him to eat greens is trouble too I honestly don't k is bow he lives with being such a picky eater :S
There can be a few different factors if you think you dragon is a picky eater. First to consider is temps.
Warmer temps for babies and juvies increases metabolism and the will eat more often. I also find if they always have food available it seems the never truly get hungry. In that case I just let them get hungry by not giving them feeders for a day, but giving them a nice bath to hydrate them. The next day I introduce some fresh collard greens in the morning. Then I feed just a few crickets or supers(depending on size and age), maybe 5 or so, in the afternoon for nourishment. Keep the bath and morning greens regular and limit you live feeders until you notice a boost in appetite. After a week or so of this I have been able to get a picky eater to regular feeding patterns.
