15 gallon aquarium suitable for for thumbnail pair?

From what I have read on this forum, Epidobates are notorious for their loud, frequent calling. If Epidobates are too noisy, then what about Dendrobates galactonotus? Other threads say their care is similar to Tinctorius, but they are less aggressive than tincs are and more inclined to use vertical space. Would they be okay as long as I give them plenty of ledges, plants, and branches to perch on? They also have quiet calls like tincs which is a big plus. The dollar per gallon sale is still on, so I can pick up a 20 gallon if that gives me more options, but a vertical setup is still preferred due to floor space limitations.
Of course, the welfare of the frogs is my highest priority and I can try to find a way to fit a more horizontal vivarium if it is in the best interest of the frogs.

Galacs can be a bit shy and are considered more of an intermediate to advanced species. Personally I consider anything in the phylobates genus to be the best beginner darts but again they don’t really suit the setup and conditions you are looking for. Plus their calls are on the loud side. It is ultimately up to you though as far as the species you choose goes. Tincs aren’t off limits to beginners they just need some supervision if kept in groups. If you can find tinctorius “oyapock” though, I think you will be happy. They are very small for a tinctorius and a single frog will do fine in a 10 gallon tank. But again, the choice is yours. No species is off limits to beginners but if you decide to get a species with a more advanced level of care be sure to do your research. Figure out what will work for the animals and for you and go from there.
