I think if you want to breed them you have to have a lot of preperation for it. As for your pair I am not going to tell you not to breed pet store fish because that's what I did the first time I bred but I am going to tell you should breed your male to another crowntail female not a veiltail. Also make sure you have to time and money and room for the fry. Make sure of what you are going to do with them when there grown up to.:)
If you have the time, money, and even more time and money for this spawn then yes. The fins of the spawn will look all shaggy... The CT also looks to have a hunchback but not sure on that one... Finding homes for +100 babies is going to be tough, especially for CT mixes. You should never breed CTs with other tail types as said, the fins will look ragged. You should only make a mix unless you're a professional breeder and I assume you're not yet. It is better to have proper breeding stock and not from stores as you do not know they're genetics which can interfere with the desired colors traced from the parents.
Since he's a CT, the fins of the fry will look a mess since their mother is a VT and their dad is a CT. Mixing the 2 will cause deformed fins and fry. To perfect the CTVT type, you must go through a lot of lines to get even rays and deforms.
