I'm almost certain that those fish are all of the sub-eqatorial variety: vatf and tatf. Of those two, I'm about 75% certain that they're vatf.
Those fish are in a tank with no substrate and a clear background. And they're tiny. This is the worst possible combo of traits for identifying a young ATF. It blanches all off the identifying characteristics on the fish and makes them incredibly difficult to identify correctly. I'm relying on years of experience to draw my conclusion on these guys. It is still very ambiguous.
FWIW, if you want a vatf and end up with a tatf, odds are good you'll be very happy with your fish. The differences are incredibly minor, and if myself and a very select handful of others on here keep our mouths shut, you might not be able to tell them apart because they're so similar.
Long story short, if you want a vatf, I'm confident that you'll be happy with these fish.
