Yes there is a way to stop the females aggression. Give her the room to set up her territory. Typically with apistogramma's the male will set up a territory large enough for several females to set up their own territory inside of his after he breeds with one he moves or is driven into another's. The male does not take part in fry rearing. the females can be hyper aggressive while guarding her spawn and the male is not welcome. Move your younger male before you lose him also. Males from othe species will probably be persona non gratia also. About the only fish you should leave with her are a small school of dither fish. The Cory's shouldn't be a problem but the pleco will eat the eggs. -----Original Message----- From: J Miller [mailto:jkmiller@gpu.srv.ualberta.ca] Sent: Monday, November 16, 1998 9:54 AM To: apisto@majordomo.pobox.com Subject: Mean Female IN my twenty gal I now have two rotpunkt - one female and one male (juvenile colors). I did have a dominant male, but the died. I thought that they had spawned because the female was bright yellow, and she was chasing the two males and the tetras away from *her* rock pile (used to be the dominant male's). I took the dominant male out because he was taking the brunt of the attack, but died about four days later. Anyway, on to my question... There are no young in the tank, but the female is still in breeding colors and keeps casing the remaining male to the edge of the tank. Is there a way to stop her from beating on the male? I no longer have the tetras in the tank, but there are two large (~4') bronze corys and three small (~1') midnight corys in there. Also, I have a clown pleco and a bristlenose pleco in there. The tank is planted with lots of rock and wood work to form many caves. I have five cocatoides (three males two females) in another tank and was wondering if I should put one on the males in wit the rotpunkt to diffuse the female's aggression. Would I have to worry about interbreeding between the two species? I also thought that I could take the male out and let him mature, then put him back in the tank and hopefully they'd spawn. Maybe I should do it the other way around - remove the female? Thanks in advance for the help!
