Hi,
Quick question here. My borelli are about to spawn again and I'm wondering if there is something I can do to get more males than females? My pH is 7.4, gh/kh are 3/4.
Thanks,
Cathy
I keep my water quite soft and ph 6.0 and have the same problem. 16 apparent females and 1 male (which I gave to a friend as soon as they were sexable).
Keep the temperature at 29ºC/84ºF and acid. You'll get almost 90% males. Like most apistos studied so far sex ratios are determined by temperature. If you want 50/50 male/female ratio, keep the pH slightly acid & the temperature around 26ºC/79ºF (see Fig. 23, pg 146 of CA1).
Hi Mike,
I bumped up the temp, but see no signs of spawning now. Perhaps I should lower it back down and bump it up again when there are eggs? Or, should I just be patient...
Thanks,

Ok, both females are guarding eggs now. (I have them in a 10g). I removed the male - he was getting abused. In the tank with the 2 females are about 4-5 juvies from the first time they all spawned. Should I remove them? Will the females be able to protect their young? I also don't want to remove possible 'target' fishes if that is the role the juvies are playing now. So, remove or not to remove, that is the question...
Now the fun begins! My experience has been that both females will try to grab all of the fry. One day 1 female will have 80% of the fry & the next the other female will have most of them. If there is an actual dominant female, she will grab them all. The nice thing is that the fry are well cared for no matter which female is guarding them.
