Aquarium Fish Wholesale

Some aquarium fish have fins that are very different in shape or size from those that are found in nature. They are the result of patient breeding carried out by aquarists over a period of years. The visual effect is guaranteed, but the fish’s behavior is sometimes altered, especially its velocity when moving around. Fish with large fins in the form of sails have little more than a remote relationship with their wild cousins, which have gone out of fashion and are no longer to be seen in tanks. The purpose of these selections can sometimes be in doubt: they undeniably result in highly attractive fish, but what advantage do they have over other stunning natural specimens?The coloring of a fish varies according to its age and mood. Some fish living in coral reefs reject individuals of their own species or a related species with a coloring similar to their own (Pomacanthids, also known as angelfishes, for example) because they consider newcomers as enemies wishing to appropriate their territory and their food supply. This is why their offspring have a very different coloring from that of adults, so as not to be considered intruders. In their desire to protect themselves, some fish adopt a camouflage to merge in with their surroundings, or, in contrast, reduce the intensity of their color to pass unnoticed. Thus, the vertical black stripes on the scalare allow it to hide among submerged branches and plants (see drawing above). In some species, the male and female sport very different colorings, enabling them to be distinguished - a gift of nature much appreciated by aquarists! This is true of a large number of the Cichlids in the African lakes. At mating time, the male can flaunt vivid colors, not only to seduce the female in the courting ritual but also to impress his rivals and scare them off. This occurs with the meeki, a Central American Cichlid - the underside of its head turns red at mating time.
