It turns out that I have the oportunity to get some Oophaga pumilio, but I have some basic questions. I know this aren't the best frogs for a dart begginer but I have had some experience with Dendrobates auratus before. I took care of my cousin's D. auratus tank while he was travelling.

So here are the questions
-I got the flightless fruit flies (D. hydei) but do the supplements are necessary? I ask this because each jar will cost me about $20. Why so expensive? Because there is only one place where you can get the supplements here.

-How should the terrarium be? Vertical I suppose?

-How many frogs should be kept together? How big for that number of frogs?

Any other recommendations are welcomed.
