One of them is a maroon clownfish x ocellaris. Premnas biaculeatus x Amphiprion ocellaris if you want to use their scientific names. This is pretty significant as it shows intergenera crossbreeding can occur among the clownfishes, which is great because every clownfish species except the maroon clownfish is in the genus Amphiprion, indicating that any clownfish species may be able to interbreed with another. The same link above did mention crossbreeds between Amphiprion ocellaris and Clarkiis and Tomatos, so yeah.
So it seems like you might be able to not only pair up designer clownfish of the same species, but also of different species. A common one should be Amphiprion percula x A. ocellaris, but a quick google could not find them. Pretty sure they are around though, you can do a bit more snooping yourself to find them. I am too lazy at the moment. XD
