I just got a new Betta today (third one now, yay!), and he's the first red Betta I've had. I don't know if he's just younger or generally small. My new red one is almost half the size of my green one. He's really cute. :) I'm wondering if he'll get bigger though? When I google red Bettas I see pictures of them looking about as big as the other Bettas I own, but my new one looks like this: http://bettafishpictures.com/images/12.jpg
He's more streamlined and his fins are less full. Is that just his "type", or what?
