Which should i get for my chameleon?
Right now he is on a diet of crickets with the odd mealworm here and there.
Also how do you keep any of these different feeders?
well it far to much info to do in one post, but generally speaking you will want multiples of the feeders listed above and provide a varied diet (like 3 minimum, if not more, the more the better).
the 2 worst of the above list I would prob say are waxworms (very high in fat content, low nutrition otherwise) essentially a treat worm and shouldn't be given on a regular basis, and the mealworms. Even though alot of people use mealworms for a wide assortment of small reptiles and small mammals because of their ease of use, price, and abundance, they also have the highest chitin content of all the feeders which is undigestable substance, and if given too much, can cause digestion issues etc.
as far as the rest, they all have their pluses and minuses, some have more calcium, some more protein, some more fat, moisture, etc. Prices vary alot between them too, as well does their care and housing, what they will eat, and how to gutload etc. I would recommend reading through a boat load of care-sheets on the insects to learn up on them and their care as its far to much for any one person to list on in a post.
