Killifish living conditions remain unstable or difficult in a marginal aquatic environment, and therefore have evolved into a strong expertise to perform better than other fish families. And surely there are exceptions as in any genus or species have different adaptations: So Aphanius and Cyprinodon live in hard water brackish, marine and even hypersaline waters ( A. iberus has been caught in the crystallizers of saline to obtain concentrations of salt in 146 grams per liter. Procatopodines and Lamprichthys exhibit group behavior.
An important study by A. Brosset on Killifish ecology of the river basin in Gabon Ivindo provides valuable information on fish in nature. The species covered are the Subgenus Diapteron , and genres Aphyosemion (4 species), a Epiplatys and Hylopanchax stictopleuron . The Killifish are considered a typical population of forest vertebrates for the following reasons:
Research findings of fertility and kinship are derived from observation of the few eggs laid and their size to the size you have parents. Furthermore the study shows that a global population is very important, because the study of a particular species is usually unrevealing.
Different species appear to be interchangeable and little specialized for performance from each other. The reproduction of the species can be differentiated by adaptation but a permanent ecological disorder is impossible to eliminate species from each other by competition. Possible catastrophic disturbances such as oil spills (Gabon, Venezuela, USA), deforestation (Cameroon), creation of arrozeros crops (Uruguay), pesticides and oil facilities and tourism (Spain, Brazil), are frequent. However, turbidity habitats elephant droppings or step or wildebeest herds of cattle and large floods are rare, and probably beneficial for nutrition and dispersion.
