How to make ADFs eat commercial frog food?

[tgampper]

Tetra makes a product called Repto-Min Frog Sinking Granules. It is a commercial diet formulated for ACFs and ADFs. As you know, ADFs are bottom feeders. Also, you can order a sinking pellet food from Xenopus Express Products - Xenopus Suppliers. Don't feed fish food.

Mine calls Tetra ReptoFrog Granules, and it is sinking. but my ADFs still don't eat it at all. I have no idea how to do.
now my ADFs only feed on bloodworms. I don't know if it will lead to malnutrition or not.
