Sunbird73 Posted August 3, 2011 Report Share Posted August 3, 2011 Found this online and found it interesting, so thought I would share with the cacatuoides enthusiasts out there... In mate-choice experiments females of the Neotropical cichlid Apistogramma cacatuoides unerringly differentiate between males of different populations and a red aquarium strain. Females use male colour traits to choose their mates. The preference of wild females for red-coloured males varies from 3 % to 69 % dependent on geographical origin, whereas aquarium-strain females prefer their own bright-coloured males in about 90 % of cases. The preferences of wild females show significant differences depending on their origin and following a geographical gradient. The high degree of stability in assortative mating behaviour in female A. cacatuoides may indicate incipient speciation processes link where you can read full research paper (1951) http://www.aquaboards.com/content.php?58-Female-cacatuoides-color-discrimination-in-Breeding I wonder if this extends to red tail vs. orange tail variants as I suspect my red tail female is not interested in my orange tail male...

the-obstacle Posted August 3, 2011 Report Share Posted August 3, 2011 It would explain why Ryan's female got the crap beaten out of her in my tank and just didn't take to any of the males. Quote Link to comment Share on other sites More sharing options...
