that doesn't mean there's no cambodian in him.
If you look at the differences in the bodies and head shape you notice lots more patterns between the fish.
I swear we need an American breeding class with defined traits.
A delta has one even spread of the rays coming out of the tail, a half moon will have two gatherings of rays coming out. Half-moon, Heart-moon and Double Tail are all more alike. (the ones that are between halfmoon and double where they have a deep inwards notch are what I call Heart Moons)
Definitely a delta, american breeding stock. I've a concern over water quality from the position of his inner gill sheath.
