These are probably tank bred individuals, and with all the selective breeding going on the distinctive characters for wild populations often are not useful for distinguishing them. So I guess the only real way to tell is ask whoever bred the line or do a genetic test. Having said that, the overall shape of the bands reminds me of ocellaris, but again, that might have changed with selective breeding.
Now, as for them being "real" species, in nature they surely are. There are diagnostic morphological, color and genetic characters.
