They are both really beautiful, royal blues are awesome! I think you pretty much got the tail types and colors down... except, I might guess that your boy is a Halfmoon based on that 2nd pic! He's a nipped up HM too! Is he a fin-biter? If so, definitely wait until he has stopped and there's plenty of healthy regrowth before spawning.
Are they spawn siblings? they really look alike! Where'd you get them?
The reason I'm thinking super delta is - It's almost 180 degrees but not quite and the ends of the first and last rays are a bit shorter than the rest. Fin damage is from shipping I'm guessing. There is some regrowth this week. I'll have better pics in a few days. They are related but not sibs. I'm waiting on more info from the breeder. Apparently there is some show(s) keeping everyone busy.
