I have never owned dart frogs before, and only recently have I been looking at them. I have an exo terra tank thats 18x18x24. I want one of these three species, but I am most interested in D. azureus. Can D. azureus be kept in groups? I am confused as one source said as long as you have one female, you can have 2-3 males, while another said only 2 males or a pair. Same story with the tinctorius, but it said to be cautious. As well is the tank big enough for a group? If so, how many darts? The screen top will be replaced by glass, so don't worry. And is auratus bold? I heard they are shy, but become bolder in groups. Can they be as bold as tinctorius or azureus? Thanks.
