Sorry, I did not get to this earlier. I don't visit here much.
What is the best starter frog? It is a common question. I would say any auratus, azureus or tinc species.
Before you even get any frogs get some fruit fly cultures. Don't get the crappy ones you see at the pet store. I can help you out if you need some. Learn to culture fruit flies first and foremost. The frogs are very small and fruit flies are the best and easiest food to get for them. Pinhead crickets are ok to use sometimes, but have a lot of chitin (sp) in them and are not best. Once you get fruit fly culturing down, you are ready for frogs.
There are a few people locally (with in 2 hours from the Twin Cities) that you can get some frogs from. The frogs require a well planted, well draining tank with temps between 72 to 78 degrees. Humidity should remain above 80%. These tanks are called vivariums.
The best website for searching information is
www.dendroboard.com. Spend a lot of time with the search feature, then ask questions if you can't find the answer. You can always contact me if you like. PM me and I will give you my phone number. I am just getting back into the hobby and after a year and a half with no frogs it is fun to be building new tanks.
