I think Mushu is a Delta. His fin shapes are very similar to my Odysseus (who also never truly flares), who is definately a Delta. He is beautiful!
I am not sure about Hu, he looks like a very nice Plakat to me, but I am not good at identifying females, either, so if he is a she, I could be totally off base.
