needle fish will certainly not work well with neon's, they will murder the neon's

blendable fish means that there has to be two different colors in order for the color to blend (red fish+ blue fish= purple fish). If they are the same color, a blendable fish will also be that color (red fish + red fish= red fish). overall it is still a surprise at how much the color blends especially if the fish has multiple colors.
