worried about my male pyxie

Hi and sorry it took so long for somebody to answer.
it is absolutely normal. Frogs, just like any other animal, are very good in controlling their food intake, they eat only what they need.... very different from humans lol
When they are young and small they need to grow fast, because it is eat and grow or be eaten situation. They consume lots when they need it. As they grow, their nutritional needs change and they gradually eat less and less, often go off food for periods of time, that usually corresponds with seasonal changes. It is important to keep an eye on your frog, if looks healthy, don’t bother, don’t stress out, you will see when he is hungry.
as example, my big boy about the same size as yours, goes to sleep for weeks at the time, not actual eastivation, because the conditions of the tank is not suitable, he just sleeps. This winter for example he ate may be 5-6 times from fall til April, woke up really hungry, ate really well for couple weeks, now he is slowing down again.
You just need to monitor general health and what food you are giving. If good lean food, a frog looks healthy, it is all good.
