Is This Possible?

[kribensis12]

Okay, most people say, to sex yellow labs, that the males are bigger, and more colorful. Well, i have a obvservation that may make it easier to sex them. My biggest fish, is a male, and he is probably over 3 inches, dark yellow, dark black fins. Well, there are 3 others in the tank, asll smaller than him. They are a lighter yellow, lighter black fins, and their throats are white. Could the white throats be a indicator of sex?

There are variations of color especially at different collection points in the lake. Some with black on the top fin and some w/out. The spots aren't a good way to guess sex. It's a 50/50 shot.

Well, they are brother and sister, which is why I ruled out different collection points.

i know my female mouth brooders are all white on their underside of their mouths. probably due to the stretching their mouths do whilst holding the babies. i noticed this myself when i had my peacocks holding. might be onto something

When mine were holding their buccal cavities were white on the underside as well. Not so much when they aren't holding.

They aren't holding, and it's pretty white.
