How long ago did you change the substrate and clean the enclosure? What is the substrate moisture level? Is there any driftwood or moss?

Could be that the frog ate something within the substrate that may have put off eating like a large fiber while chasing crickets.I believe it makes their tummy a little upset and you may want to give the little one a honey/pedialyte bath. This will also give you a chance to give the frog a good looking over.

I don't have Tomato Frogs, but my Pacmans seem to do this when they have something that they need to poop out. Especially if its one of those fibers.
