Wish I could give you advice, but we were lucky enough to not have tree frog tadpoles, just Florida Southern Toads. But yes, its funny how even the most cheapest species of frog can end up costing you hundreds I feel like that's the catch, having you spend more money at their stor I have Four Fire bellied toads, my girlfriend named them all. They all cost 7.15 per frog and ended up costing me more than $400, the main cost was the gravel and decorations. We actually picked up the 55 gallon tank with its stand and screen for 55 bucks at our local family owned petstore, was great and looks great. We plan on adopting the last Fire Bellied this weekend.
Excited to see how it goes and I will check up on this thread every day or two!
