First....congratulations on your new frog!
Do NOT feed meal worms/ super worms as a staple diet,only as an occasional treat!!! The outter skin (chitin) of the worms can become a mass and cause compaction in the frog and possibly cause death.
Offer food nightly. Try night crawlers, dubia roaches, crickets, fish(mollies or guppies), You can also try using the food offered by Samurai which is a powder that you mix with water to make a dough. Depending on the frog's size, you can also offer it a pinkie mouse once every 2 to 3 months as a treat.....but only if the frog is large enough to handle it!!.
I think you should also visit the care sheets and do some reading, it will help answer some questions for you as far as husbandry goes to.
Good Luck!!!
