The first is a veiltail, looks like he has damage to his caudal as most of it is missing. He's a marble, you can usually tell it's a marble by an oddly colored gill plate. The second is a crowntail, also with damage. You can tell by the way the caudal is kind of chopped off, while the dorsal has web reduction. His coloring would be considered "pineapple," or a yellow with dark scaling.
