Well let me be the first one to congratulate you! It looks splendid. Wow! Both tinctorius (azureus) and D. auratus (black and green) will thrive in this. And you could put a rather good amount of frogs in there.
If you opt for the azureus, make sure you do not put females together. They get really aggressive when put together. Can you let us know what plants were added? Substrate? Etc?
This is one of the nicest thanks I have seen lately.
How happy Phyllobates terribilis would be in there...
