You have pretty bettas ~
If you keep them in a 1 gallon, you may want to consider getting them both a bigger tank later on. 2.5-5 gallons is the best to give them. Well, that is what I have learned from my experience so far, though i've only been a betta owner since....late June. Haha
That's kinda cool getting a different type then what you expected, :D
