Dart Den

I purchased a d. azureus from our yearly reptile show about a month ago. He's doing well and I've been raising fruit flies and springtails for him. When I purchased him, I was told that I could eventually add a d.leucomelas to the enclosure. But, from what I've been reading, that does not seem to be the case. Does anyone have any suggestions to another pdf that I could add? He's currently in a 29g setup.

Thanks!

Give him a D. azureus female, I wouldn't mix species in that size tank.

Thanks. I like the excuse to get a larger tank!
