Suitable Dart Frog Tank?

[Helios]

I'm seriously looking into getting some dart frogs. I know generally variance in species can impact this, but what I'm wondering is, in general, how many could be suitably kept in a 12" x 12" x 18"? My plan would be to maximize the vertical space by creating different levels throughout the tanks. Thanks for the input!

the exo terra 12x12x18 is about a 10 gallon to 12 gallon tank, you
could put two of the larger darts such as the dendrobates or three
of the smaller thumbnail species.

I have one thumbnail dart frog and love to put him in a micro. wish they made 12.12.12 sized the 18.18.20 too big for one frog.

I would look at a pair of Thumbnails. That's all I would put in a tank that size and have a few. It too small for Dendrobates IMO.
