In German Blues (of which the blues are a color variation) the female will have a very obviously pink belly which turns almost red as they get closer to spawning. But this is a problem as well, since under these names both hybrids and completely different fishes are sold. On the other hand, resources that females convert to the production of eggs (e.g., nest sites and the forage resources associated with them) will be valued differently by females depending on their reproductive condition at the time of the contest. Contest outcome matrices in terms of payoff to larger contestant. Powerful external filter and regular water renew is a must in this case.

A fixed inclined plane will do perfectly for this purpose. The way females fight has been overlooked. The competitive pairs always consist of a larger male and a smaller female. Here again, our results were consistent with the WOAM, because the duration of female contests was unrelated to RHP asymmetries. It’s not difficult to grow the juveniles, if you provide them with sufficient amount of food. Herichthys cyanoguttatus natural areal is in North America and North-East of Mexico. Don’t feed the fish too much to avoid tank water contamination. i was told that any fish that has a white shape on its anal fin is a male. The same correlation between female aggressive intensity and reproductive cycle has been repeatedly reported in mammals (Ayer and Whitsett, 1980; Hirth, 1977; McDonough, 1994; Murie and Harris, 1988) and birds (Breiehagen and Slagsvold, 1988; Gowaty and Wagner, 1988).

In addition, eight out of 45 female contests were won by the smaller fish, and 27 contests were won by the larger (Table 2). Fry available soon!! In light of our results, future studies on fight theory should consider sex-specific differences in fighting strategies.

In addition, males, but not females, followed SAM predictions regarding the fighting strategy of each contestant in terms of conventional behavior. In support of this notion, Holder et al. However, we opted to use discrete time intervals because we were often unable to know the exact “end” of the fight, because the winning and losing roles often slowly emerged over several minutes. Flowerpots are readily accepted by cichlids as spawning sites and refuges (Itzkowitz, 1985); thus, we used them to promote fighting. They have taller body as well as males have a pronounced nuchal hump. The male will defend the territory and after 3 days the fry should hatch out. These latter two variables were recorded and coded in seconds. Although intrasexual female contests are not rare in nature, there is no apriori reason to expect that female contests follow the same patterns discovered in male contests. The thing is that large fish requires a large tank, otherwise it won’t reach its maximum size. Sometimes the female digs a pit and uses it as a nest. The observers then sat behind a blind, kept written accounts of each contest, carefully monitored fish for injury, and determined at what point one of the fish was victorious. In the present study, we staged intrasexual male and intrasexual female contests using monogamous, biparental Texas cichlids, H. cyanoguttatum, to examine whether the relative body size of the opponents affects the durations and the outcomes of the contests of both sexes similarly.
