wooopsy...I posted that before I was finished.
Anyway, its been quite a ride with these guys, but they are wonderful little creatures and worth all the time, money and effort.
Now getting back to Apollo, since the frog had been ill from red leg prior to you buying him I'd march down to that pet store and in the nicest way possible and give them your vet bill for selling you an ill frog!!! When you purchase a pet from a pet store it is given that you are buying a healthy pet that has been checked by their vet routinely. If you buy one that does have health issues than they are responsible!!!! It's the law!!!
I bought my first puppy 16years ago, whom I still have, and he had an undecended testicle. This condition increases the risk for testiclular cancer and I had to have him fixed ASAP. The pet store was responsible to pay about 90% of the cost. I bought another dog from the shelter who had kennel cough and they too were responsable for most of the bill if not all of it, I can't remember I had her for 21 years and she was 6 when I adopted her, she was a peek-a-poo we named pookie, we called her Methusalah though since she was so old!
So my point is that the pet store you bought Apollo from should be responsable for the vet bill and the cost of the treatment.
I don't know how far you are from me , but if you are close I'd be willing to go with you to the pet store, I am a pro at this!!!LOL
Good luck and keep us updated on Apollo's recovery and post lots of pics
