these are 2 pics of my latest zebras.the fish are 2,5" TL and now they are more healthier and fat...The pics are during the acclimatization from the trip from Germany to Greece some time ago....
What do you think of them?

a)


b)

I would have a guess that the top one is female and the bottom one is male. My thinking is that the top fish appears to have more curve in it's pectoral fins and the bottom one less, apparently this is another way to sex them. I have noticed this difference in my lot but I guess the only way I'll know for sure is if they breed.

This is just my oppinion, I really should leave this sort of thing to the experienced members as I always get it wrong.

Unless they are very skinny, immature females, I think both are male. As for the pec fin thing, my best and biggest male has very curved fins, so I don't like to go by that. Try to submit side shots showing the odonotodes and the shape of the forhead. I think that would be better for me to better judge.

Husky_jim,
In my humble opinion ,they are 2 males, but to be absolutely sure you would need some more overhead shots in focus (to see the leading pectorals) and good side pictures to see the same and the cheek odontotodes .

I think they are two males, based on the thickness of the first pectoral ray, and the proportional size of the fins.

For sure they are immature and needs time in order to tell exactly.They don't have 'male' cheek odontodes and also mine impression was for two males since yesterday which the one of them pass the hole day inside the dominant male's cave......

I guess i have to wait.
What do you think?

My Guess goes for Top Female, bottom male, purely on the shape of the pectorial fins!

cheers rob

both male i would say........but hey ,what do I know ,Im a discus buff lol
