so sorry for your loss MeTres, RIP Cody.

as for other things - I can tell that people on this forum helped me way more then any vet by far! there is nothing like hands on experience and advice from breeders and keepers who know what they are talking about. there are just a few vets who are specializing in herps, and out of them only small percentage know anything about frogs. I know that for a fact but that is in US, same in Canada, I don't think there are any board certified herp vets, so the best case scenario you will be dealing with general practice vets who may have been to a few exotic animal conferences and read a few book about exotics, but with animal this small and having such a small possibilities to do anything surgically I doubt vet would help anyway here.
advice on feeding outside the cage - well this may work for some, but in some instances - they will better starve then go there, why to get them more stresses then they need to be, in my particular case - if I feed mine in separate container he would be starve to death, only 1 out of 4 frogs is ok with tong feeding and that is under condition he is in his cage.

so my advice is - love your frogs, do your research - find ALL that you can on your particular frog, ask for advice no matter how stupid the question may sound, listen to what people have to say and do your very best for your little "baby" - provide the best conditions he can possibly have, and be prepare to pay as much as you need for all that stuff, including visit to a vet when you know it'll help.
