I was windering if its ok to start feeding my 2.5 month old ambilobe mealworms now ?

I fed my chams mealworms from an early age with no ill effect, but if I knew what I know now, I'd probably avoid doing it again.
Mealworms are tougher to digest (due to the chitin content) and are also not very nutritious feeders (high fat content for relatively low protein, and the gutloading potential is limited).

They can be offered as a supplemental treat provided the cham is healthy and will be able to digest it easily, but if you do decide to use them try to pick out the recently molted ones - supposedly the chitin is easier to digest before it has hardened.
Feed them sparingly - a young cham will try to each as much as it can, and I suspect that if mealworms are ever to cause an intestinal blockage (impaction), it would be because of having overfed on them.

If you have the option, rather use silkworms or appropriately sized superworms.

just remember mealworms to chams are like a cheeseburger to humans, may taste good but are filled with fat.

cricks got more nutrition though.. i would have given your cham a little bit of both? I mean who wouldnt go to Mc Donalds from time to time?

Try some small silk worms or small super worms.

this must be the metaphor thread,.

i wouldnt feed more than a couple mealworms a day, base diet on crix, but also look into it. there are lots of feeders out there. wax worms, phoenix worms,silk worms, BB flies, and a load of others.
