Hi Sarah,
Sorry your frog died
It takes a ton of research prior to purchasing any frog.
You will gain addition information to add to your current experience by reading and collection absolutely as much general information about frogs as possible and even more specific information about the frog you are planning to keep. Think of it as a research project !!! Thank goodness for the internet! The more you learn the more prepared you will be for some of the problems that WILL arise and to deal w/ the conflicting information you WILL run into. I'm sure you know you don't want to re-use this enclosure without breaking it down and completely sanitizing it.

Also here is some information that will enable you to be prepared as possible moving for forward.

If you do not have a herp vet nearby ( able to care for frogs ) here is D Frye’s contact information. And a list of common “medicine cabinet” supplies that should always be kept on-hand when keeping frogs.

If you ever have to email him, he will need the photos and detailed information regarding eating, pooping, housing. He will get back to you promptly. If you have the basics on hand you will be able to treat most of the common froggy problems w/out delay !!!

Hope this helps! Keep trying ..........but they , sadly, do not come with directions.
If you need help w/ other great frog care links ( besides FF ) ...let me know. As I personally have a zillion links saved and very topically organized. A little OCD goes a long way !
