German blue angels are definitely a beautiful Fish, it's actually the only color mutation that I would consider keeping. The reason I want leopoldi is because my dream is to have all three species with there own tank set ups one day. I've already kept and bred wild pterophyllum scalare and the next step would be the leopoldi than moving on to altums.You could go that route, although I was referring to German Blue Angels. White with black stripes and a hint of blue.
