Hi broncosno1 I can help you a bit with the genetics...
What were the actual crosses for the spawns?
ex. FatherxMother, Red VT x Cambodian VT
I've got a pretty basic write-up on the colour genetics on my blog. The sources are more in depth I kind of combined and summerized the information.
As for tail type genetics VT (veil tail) is the dominant tail type. CT (crown tail) is an intermediate inheritance. Basically if you cross a VT to a HM you'd increase the spread of the VT but it would take a lot of work and inbreeding (the inbreeding is common in
betta lines) to get back to HM spreads again. If you Cross a VT to a CT you'd lose the 180* CT spread and would get what's called a Combtail where the extended rays are present in varying degree's but none of the fry have the 33% reduction nessecary to be classified as a CT.
That was sort of a vague explaination but if you'd give us some more info on the parents and they're history (Pet Store or Breeder) it'll help us out
