Honestly, and not trying to sound mean.. but that male is not one you should breed... at least if you are wanting to be able to sell the juvies from the spawn.
Dorsal is too thin and bumpy, anal is just a mess and the caudal.. well.. it's not even close to being nice. Sorry it's blunt, but that isn't even considered a combtail, just the unfortunate happenings of people mixing tail types and not knowing how to do it properly, etc.
He is cute for a pet, but for breeding I would stay clear of him as it's honestly not going to get you anything - you will spend hundreds of dollars setting it up, hours a day on water changes and regardless of the female you place him with it will take a few generations to get it semi-cleaned up. Unless you have a local pet store that isn't picky on the fish they get, you will have a very hard time finding homes for the first couple generations.
If you are very set on breeding him then I would try to look for the best HM female you can find - you will end up spending a pretty penny to find the female that you need to begin to clean him up, as she will have to be perfect - 180, wide dorsal, even anal, straight topline, etc. You will also need to find a female to compliment his colors - blue with red wash is undesirable in anything outside the pet trade, so you will probably do best in finding a female with no red to her.
What is your goal in breeding?
Here are some combtails that are "ideal", combtails aren't something most people seek and look to buy, so you're best bet is to get rid of the combtail and try to even him out. If you want to work with combtails then I would suggest learning about the genes and find out how to breed for them and breed them proper. As you can see the difference between your little guy and these true combtails -
