I saw a YouTube video of a dwarf frog eating a betta, so I'm not sure if I go that route. If u opt for the 29 gallon biocube, would that be a better option? I may only include 3 frogs.

What species, if any would be best? After watching some videos, I definitely noticed they seem to stay on the bottom, which I questioned if just a shallow tank do?

I'm just doing my research now, as i want everything ready before adding anything. I really like the dwarf frogs, but is there any other aquatic species that would do well in either a 14 or 29 gallon biocube?

Or can I set up some sort of half and half tank? I would rather full aquatic. I miss having a tank set up. I really would like a few live plants in the tank.
