Genders of these L 204, 260

Post by Speedy1985 »

I'm just curious as to what you think the sexes may be for these 2 groups. The 204 are adults and wild caught. The 2 smaller ones are easily 4-1/2" and the larger 6". The smaller 2 definitely have odontodes on their back, so I'm assuming male. I don't see any on the larger one and the body shape seems to be much wider. I just didn't think that females would get that big.
The 3 L-260 are about 2" juveniles, so I'm not quite sure if there's a discernable difference yet.

L204 - 2 males and one female.
L260 - maybe 2 males (sides) and one female (middle). But I can't see the pectoral spines clearly to see if the males are showing odontode development. So I'm not certain in the L260s.

@fishguy 1978, they are loading for me. Can you still not see them?

Cheers,

Thank you Eric. I suspected the same with the 204, now if I could just get them to "like" each other!

I see what you're saying about the 260's.

Is it the broader head, in both species, that you see as a female and more pointed snout in both as male, without regard to the odontodes?

The males' caudal peduncle odontodes are very obvious, so sexing them is easy. The large size of the third fish, without obvious odontodes, really says it's female.

And as far as liking each other, =)) We all have that problem! :))

Yes, that's what I'm going by, but I don't have confidence in it.
