i have a 100 gal setup with 9 occupants currently 4 JD's, 4 Cory's, and 1 pleco. I was curious if I could introduce a couple of Hemichromis lifalili into the tank without too many issues. The JD's are about 2.5" currently and haven't paired off yet.
depending on if you are planning on having breeding pairs. If you want 2 pairs, I wouldn't do it. If they are all male or all female, you could get away with one or two. I think the dempseys breeding would cause alot of problems.
