Sorry I just found this. Get a jar of wingless fruit flies at your local pet store immediately. Be sure to pick one out that has the most already hatched. Get a small tank preferably around 5 gallon or smaller, make a fine mesh screen to keep the fruit flies from escaping. Put the froglet into the tank, shake as many fruit flies as will come out of the jar, and let the froglet eat like this over night. You should see a profound change by the next day. Keep feeding this way for a couple of months at least, maybe longer depending upon how much the froglet grows. At the age indicated by the photos even the smallest pinhead crickets are too large for this little one to eat.
