Sorry Still learning the ropes
I have a 75 gal standard 18H 18L 48W
I Got all of my fishes at my lfs and most were in the mixed peacock tank but I do know that I have 2 blue dolphins, a yellow lab, 2 OB's, an albino, 2 cat fish and a pecosimus. The rest I have to guess at I have a dark blue/black one with strips down the side that I think is a red shoulder peacock, a bright orange one with spots on its fins that I think is a dragon blood, a yellowish green one that I think is a yellow Jake and one that I am sure is common but I am not sure what itIs but I call him Robin because the color is simallar to the bird. A redish Brown with strips down his sides
I'd swap out the duplicates for other haps and peacocks that look nothing like the ones you have but are well colored (all male). This would be so they don't fight. And maybe more yellow labs to get about 12 individuals.
