How to make ADFs eat commercial frog food?

[Pekams]

My ADFs don't eat commercial frog food completely. Occasionally they vomitted commercial frog food as soon as they swallowed it. They seem to be only interested in bloodworms, however, eating bloodworms long time may cause malnutrition. The commercial frog food I use is Tetra ReptoFrog.
Is there any way to make ADF eat commercial frog food?

Commercial foods like this are often difficult to digest for frogs. However, you might be dealing with the frog having developed a preference for other foods. I would keep trying to make them eat the commercial diet - don't give in by giving them other foods too until they're established on the commercial diet.

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.
