Gorgeous fish
You seem to have got the types confused, an oranda has a dorsal and a wen, which can extend down the cheeks and often does, a ranchu has no dorsal and a wen which can extend to the cheeks and a tail which curves at an angle to the body, a lionhead has a straight tail, no dorsal and a wen.
That's definitely an oranda, a very cute chubby one at that LOL.
How big are the fish? and how old are they? my biggest goldy at the moment is a black moore, 28 cm (11") nose to the tip if his tail, about 8 years old now.
