[Peter Finke]

Yes, 4 or even 6 males to 1 female is a bit bad a ratio. And your tank is rather big (Couldn’t you separate 3 compartments?). But do I understand it correctly, the female is much bigger (and older?) than the males? Then you must wait a bit unteilthe amles try to display in front of the female. Then it’s time to separate them; gstringly ive her 1 or 2 males, and when one male is occupying the cave and displaying with the female, remove the second. Then you have the chance for young, but hardly with the ratio 6:1. As long as they are too young they will not molest the female, but soon they will.
