I also keep sauvagii so hopefully we can share some info. You have had them a long time and still don't know sex? Do they call? Wondering if you have two females? I have three males-for sure-and one that I hope is a female. I see that you are also in Socal-maybe a trade is in our future someday.
A question I asked here recently-do you tong feed the monkeys? I can't get mine to even consider it. They ignore the food or turn away-whereas for moving food items they laser focus and will stalk all over the tank. The problem with that is that dubias don't move a lot, they tend to freeze when being chased! Therefore my dubias are getting ahead of my ability to use them
