The picture shows he has orange fins.... if he really has orange fins, IMO that's a rare combination. Getting a sibling female would keep such combination.
He has great fins. Unfortunately his anal is rather long - easily fixed with a few generations of selective breeding. Further he has some foldings .... look at the anal fin, just at the end of the ventral. then there's at least one about 1/3 from the top of his caudal. Just hope those folds aren't genetic.
Nevertheless, in general he has great fins.
