A. borellii female gets a blue sheen

[JosVermeulen]

There's this A. borellii female that looked like this 2 years ago

and she was like this a bit over 2 months ago

But now she looks completely like this

She's wild caught, but the blue sheen seems to be a male feature. Does anyone know what is happening here?

It could be old age. As female apistos age they often take on male features - like the blue sheen and slight spade-shaped caudal on your female. I don't know, maybe it's hormonal.

Hi all,

I think it is old age as well. When I kept Apistogramma cacatuoides some of the old females developed "male" characteristics.

Have a look a this thread <"Cacatuoides changing sex?...">.
