Good to hear. He may be wanting prey that move a bit more.

Everyone should keep in mind that they can sense seasonal changes even if the enclosure remains stable. They will slow their eating when winter sets in, but this is not always the case. Every frog is different and I have some that eat year round and others that will go down for a month at a time even in the summer. Force feeding as was previously stated is only a last resort.

Be sure to rinse the frog off after an electrolyte bath. I will also ask that you keep an eye on the frog's urine while being bathed. They will usually replace stored water kept in the urinary bladder when given the opportunity. Dark, strong smelling urine can be an issue because unlike mammals, their kidneys do not produce concentrated urine. Dark colored strong smelling urine could mean slight dehydration infection. Lacking in dietary supplementation or improper supplementation can also result in dark urine as water soluble vitamins that are not absorbed are expelled. Be on the look out for mucus in the urine as well.

If the picture above is resent I would say you should not be worried yet.
