sounded like male GTs aren't the player type that date a few female simultaneously.Auballagh said:Won't work. When a pair forms up, the male and female pair will attempt to drive off all non-paired Green Terrors (or other Cichlids) from their claimed spawning territory. That territory (unless they are kept in an indoor pond or something....), is usually larger in bottom size, than the confines of an aquarium.
Non-Paired Green Terrors with no room to escape from the spawning pair in the aquarium, will be killed.
In species with a lek mating system, both males and females are polygamous. One such group is the tribe Ectodini from Lake Tanganyika, a diverse group of mouthbrooders that includes Ophthalmotilapia, Cyanthopharynx, Callochromis, Xenotilapia, and several other genera. Males of these species build large crater-like nests in the sand floor, each nest immediately adjacent to another, such that large areas of the sand floor are virtually confluent with breeding sites. A male will attempt to attract a female to his nest, and if successful, breeding will ensue in the usual manner- eggs being deposited, fertilized, and taken into the female's mouth. However, before the female has released all of her eggs, she usually leaves the nest, and goes in search of another male, and then the whole process is repeated. In this way females of these species carry multi-paternal broods, which increases the genetic diversity of their progeny. You need a very large tank to see these behaviours in captivity.Auballagh said:...Not to say that in New World Cichlids, there aren't some Real Players out there!

Harem breeding is not at all peculiar to just these new world cichlids. Pretty much any substrate spawner can be polygamous. As far as green terror, yes there are numerous examples on the internet of people keeping a male with 2 or more females and having the male breed with all the females over a span of time. But usually you need big tanks and a lot more then just 3 or 4 cichlids in the tank for them to coexist.Auballagh said:Not to say that in New World Cichlids, there aren't some Real Players out there! The mouth brooding Geophagines are one such type, with the dominant male spawning with multiple females in a 'harem' group. Apistogramma cichlids are yet another type that do best when kept in Harem groups.
