I don't think it's chuckys bride aka pink hippos as there's really no pink towards the end of the circle. The second picture looks like frienkenstiens but the center is not green enough..maybe it's the camera? The third picture I don't think are alpha omegas as there are no speckles like marks. I thought they might be fire and ice but as we all know the center is not blue and has speckle like designs on them as well. Im not 100% sure of course cause theyre not in my tank but basically my conclusion is that these are just part of the group that has not been identified yet which means you can be the first to name them yourself!
