He's about 18 inches and 435 grams, idk what age to start transitioning to more veggies, he loves his supers and dubias, should I start starving him so he only has the option to eat salads?
So he's gone from 490 down to 435 while gained an inch ? That can be normal, he senses that he doesn't need quite as much food or else the pinworms could be causing a slight weight loss. Being that he's breeding age + size that could factor in as well [ hormones ] But just skip a few bugs per feeding and do offer salads. Try kale, collards, turnip + mustard greens along with squash, green beans, endive . Most dragons really like kale though.
