I don't see why you shouldn't breed this guy. Yes he has bent top line. But that is normal for a DT. IMO he has great fins - upringht dorsal, 180* spread caudal, fairly equal anal, wide ventrals. I would breed him to a steel blue/cambodian with a lot of irid.
His color (cellophane) could be cleaner - he has black smudges on his body. I love the irid sheen on his fins. Other than that, he looks great.
Anal fin could be straighter, this fish came from a pet store fish we spawned. His father was bought at a LFS. This fish won Best of Show halfmoon male in the new breeder class.
Exactly my point.
Btw, what do you mean by straight anal? I don't see bent rays - wavy, yes, but not bent
