2 Months ago I got an 8 and 4 month old WTFs. I was told the younger one was older over the phone but when I got him by package he was much younger.

Because of this I kept them in separate cages. Now they are 10 and 8 months old and getting similar in size (tho the 10 month old is definately fatter) I'm wondering if I can put them together. I'm guessing the younger one is male because it started croaking a few weeks ago, and the older one is female as it hasn't ever croaked.

They would be housed (the larger one is currently here) in a 18x18x24 Exo terra.

Are there any signs I should look for if the larger one is attacking / bullying / or just stressing out the smaller one?

Also I'm wondering how I should do feeding.

Currently I feed:

Monday - Calcium /w D3 dusted Crickets
Wednesday - nondusted Superworms OR Mealworms
Friday - Multivitamin dusted Crickets (sometimes Waxworms)

For feeding them crickets I put them in a different small cage for feeding to ensure they eat them.
But for super/meal/wax worms I put them into a dish that they help themselves to.

My problem is once I have them in the same cage, how do I ensure they are both eating the worms I give them? Should I get some forceps and manually feed them?

Thanks in advance!
