I am planning on setting up my first PDF vivarium sometime this year and I am just doing some preliminary research. I am fond of the D. leucomelas and my wife really likes the D. tinctorius “French Guiana Cobalts.” So my question is, would I be able to house a pair of each of these in a 40 gal breeder tank? I plan to have the water feature (pool and waterfall) in the middle of the tank to kind of divide the land areas. If this would work, would a pair of each be the max I could house together? Thanks for your time.
