Baby Borelli sexing

Hello,

not to active in this forum, but have a question now, since my Borelli couple have just delivered their second group of about 40 offspring.

The first group was only 10 big, but they are all still a live in a seperate tank. They are growing nicely, but i wondered if there are pictures of the different agestages of the Borelli's?

Next to that, i can't seem to find any specific info on sexing the little ones. What are the best pointers as to determining male/female? I know 1 is a male for sure. He has some color and is "the man". The others, i don't really know, but would love to know!

I hope anyone can help me out...

Best regards!

For me its very hard to sex juvenile apistogramma reliably as they all tend to stay in the female coloration until mature. The exception i've found is with species that have dorsal fin extensions in the males (like cacatuoides and macmasteri) sometimes you can see these early on but for the most part its very hard sexing apistos till they are grown out.

Thanx for the replies!

A few days ago, i added some fresh Brine Shrimp. They loved it and what i noticed clearly was they put on their best dresses! The females turned bright yellow and the males lost the stripe on the side and went in to there blueish/greenish with yellow. Great way to sex them!
