Cichlids are efficient and often highly specialized feeders that capture and process a very wide variety of food items. A complex set of muscles allows the upper and lower pharyngeal bones to be used as a second set of jaws for processing food, allowing a division of labor between the "true jaws" ( mandibles) and the " pharyngeal jaws". Ĭichlids share a single key trait - the fusion of the lower pharyngeal bones into a single tooth-bearing structure. Generally, however, cichlids tend to be of medium size, ovate in shape, and slightly laterally compressed, and generally similar to the North American sunfishes in morphology, behavior, and ecology. As a group, cichlids exhibit a similar diversity of body shapes, ranging from strongly laterally compressed species (such as Altolamprologus, Pterophyllum, and Symphysodon) to species that are cylindrical and highly elongated (such as Julidochromis, Teleogramma, Teleocichla, Crenicichla, and Gobiocichla). Īll cichlids practice some form of parental care for their eggs and fry, usually in the form of guarding the eggs and fry or mouthbrooding.Īnatomy and appearance Relationships within the Labrodei Ĭichlids span a wide range of body sizes, from species as small as 2.5 cm (1 in) in length (e.g., female Neolamprologus multifasciatus) to much larger species approaching 1 m (3 ft) in length ( Boulengerochromis and Cichla). Many cichlids introduced into waters outside of their natural range have become nuisances. Their diversity in the African Great Lakes is important for the study of speciation in evolution. Cichlids are particularly well known for having evolved rapidly into many closely related but morphologically diverse species within large lakes, particularly Lakes Tanganyika, Victoria, Malawi, and Edward. ![]() Cichlids have the largest number of endangered species among vertebrate families, most in the haplochromine group. The family also includes many popular freshwater aquarium fish kept by hobbyists, including the angelfish, oscars, and discus. Many cichlids, particularly tilapia, are important food fishes, while others, such as the Cichla species, are valued game fish. The actual number of species is therefore unknown, with estimates varying between 2,000 and 3,000. New species are discovered annually, and many species remain undescribed. At least 1,650 species have been scientifically described, making it one of the largest vertebrate families. This family is large, diverse, and widely dispersed. The closest living relative of cichlids is probably the convict blenny, and both families are classified in the 5th edition of Fishes of the World as the two families in the Cichliformes, part of the subseries Ovalentaria. On the basis of fossil evidence, it first appeared in Tanzania during the Eocene epoch, about 46–45 million years ago. Cichlids were traditionally classed in a suborder, the Labroidei, along with the wrasses ( Labridae), in the order Perciformes, but molecular studies have contradicted this grouping. It contains important information about order fulfillment time, shipping speed, and other pertinent details.Are fish from the family Cichlidae in the order Cichliformes. *****Please review our Shipping and Handling FAQ prior to placing your order. Scientific Name: Apistogramma cacatuoidesĭiet: Small flake or pellet, small frozen or live foodsĬompatibility: Schooling fish, plecos, small catfish, livebearers, rainbowfish. Dither fish such as small tetras and livebearers can be used to provide parents with targets to chase. ![]() Fry are guarded by one or both parents for several weeks. Cichlid caves, overturned flower pots, and leaf litter work well.īreeding is achieved by feeding live baby brine shrimp to an adult pair and providing a proper tank setup. The tank should be furnished with several caves or nooks to protect and spawn in. A sandy substrate is necessary due to their earth-eating habits. ![]() ![]() Apistogramma cacatuoides is a larger species of Apistogramma and will work well as a pair in a 20 gallon tank. These fish are a wild strain and are not the tank-bred variety with bright red or orange fins. Wild populations have subtle blue and yellow colors with a few orange spots on the caudal fin.įemales will turn bright yellow with black fins when in breeding dress. Remarks: Apistogramma cacatuoides is one of the most popular Apistogramma species. ![]()
