Hi
Welcome to Frog Forum.

I see your post is unanswered. Sorry about that.
There are many very important / and good questions that will come up regarding their care.
You simply have to read several basic "care sheets'.
Then narrow down your reading once you have decided on the species you are interested in keeping so that you can feel well informed in its care - specifically.

It is really the best way to approach this, beginning with a good dose of the basics and independent research will get you started and help to prepare you to make the best day-to- today decisions regarding their care.
