just one of the color morphs they have i have some all blue ones and all i started with were red rili. you can eather pull the blue ones and just keep the red or just keep them all together. i keep mine all together some times i end up with more blue some times more red.
i have ended up with mostly blues. i did leave part of my rili in another tank and had reds there so i mixed them in a new tank when i moved things around we shall see what i end up more with since the biggest majority is blues now
