So I'm legally colorblind and fail all of those stupid circle/dot tests after only one or two tries, but I can still see color in larger quantities. I like to keep mbuna and other brightly colored fish and am wondering if it because I can actually see the contrast that I may miss on SA/CA, PBass, FHorns, and other popular fish that I find rather plain. I also love arowanas and stingrays, but with those it's the movement that attracts me. If you test colorblind as well then post what some of your favorites are and maybe the rest of us will discover something new to try to keep.
