For all you know that's why the brevis that you're seeing for sale don't have a location or variant name specified. Somone may have gone ahead and done what you're asking about. If you're going to breed and pass on fry, you should be confident of your sources. Maybe the store just doesn't know or care enough to ask their source for this info, but then that raises red flags as well.Most of the fish I see for sale only have a common name, Brevis, Multis, ect. Is it wrong to mix variants and just label the fry as "Brevis" when selling them?
