Ancistrus sp., sexing revisited

Ancistrus sp., females with bristles

It now turns out that I was right about the young female, one of the males however turned out to be a female which im very happy about.

In the end it seems that both males and females grow bristles quite early, it is however still possible to somewhat accurately sex the juveniles by the amount of bristle growth.

The male, today:















The females today:




















They still need to put on some weight but I am hopeful about getting some fry from these next year.
