Yes, Patriot bettas are just the red, white and blue coloreds, no? That's what I always heard them refered to as. I have two females that color. But I've never heard of an amazon betta.
Do you have a pic of your girls and are they for sale? Amazons are similar to patriots with exception to the blue. Where a Patriot is blue in color an Amazon has green. Very majestic looking bettas indeed.
