Although a number of individuals have apparently claimed responsibility for the introduction of C. ocellaris into Lake Gatun in Panama, the most likely initial introduction of the species was accidental (Zaret and Paine, 1973). Baltimore, USA: Johns Hopkins University Press. C. ocellaris was extensively released in Florida not only to create a sport-fishery, but also to control introduced fishes such as Tilapia mariae, the spotted Tilapia (Shafland, 1999b; Robins, 2015). In the wild they are rapid swimmers but in the aquarium they are more sedate, often lying motionless waiting for prey. Contact me via email if interested in aquarium species ...email@example.com. Eggs were observed to be elongated, light yellow to yellow-brown and averaged 2.27 mm long and 1.27 mm wide. Tan BC, Tan KS, 2003. Reproductive behaviour depends on temperature and hydrology, and if both are favourable Cichla can reproduce throughout the year. White spots are present on the second dorsal and the upper lobe of the caudal fin. Kullander SO, 1986. Aquarium filters which have been highly recommended by customers in … They are also territorial and voracious predators, eating anything that fits in their mouth. each one. It was at one time common place to feed cichlids meat from mammals such as beaf heart, red meat and chicken. by Courtenay Jr W, Stauffer Jr J] Baltimore, USA: John Hopkins University Press, 131-161. Unit conversion calculator for aquariums: How many gallons are in your aquarium, how many drops in a teaspoon, whats the difference between a US gallon and a UK gallon, not to mention liters? Global Invasive Species Database (GISD). In Brazil, the translocation and release of species of Cichla is illegal. Schroder SL, Zaret TM, 1979. C. ocellaris was introduced into south-eastern Florida in 1964 (Courtenay et al., 1974; Courtenay and Robins, 1989). http://www.fishbase.org. Hydrobiologia, 638:245-253. http://springerlink.metapress.com/content/1573-5117/. Fish information on Peacock Cichlids, Aulonocara types of cichlids from Lake Malawi, their habitats and keeping African cichlids tanks. These large fish can easily do damage to fragile equipment, so be sure to protect your equipment as much as possible by hiding it behind rocks or other decorations. Being so very large, there are no reports yet on successful tank breeding, but they will spawn in an outdoor pond. There was a small tributary feeding the back of the bay. 66 (1), 33-40. http://www.publish.csiro.au/nid/126.htm DOI:10.1071/MF13105, Froese R, Pauly D, 2015. Butler R, 2015. Their large mouths and projecting lower jaws coupled with their large overall size cause them to commonly be mistaken as a bass instead of a cichlid. Feeding of introduced species of Cichla (Perciformes, Cichlidae) in Volta Grande reservoir, River Grande (MG/SP). It was concluded that aquatic plants provided very limited protection to native prey and are therefore unlikely to slow down the decline in biodiversity resulting from the introduction and spread of species of Cichla including C. ocellaris (Kovalenko et al., 2010). Marine and Freshwater Research. Diversity, extinction risk and conservation of Malaysian fishes. Some populations persisted briefly though all disappeared by 1992 due to temperature extremes (Howells and Garrett, 1992). Knowing the signs and catching and treating them early makes a huge difference. Willis et al. They don't bother live plants, so these can be provided around the inside parameter of the tank while leaving plenty of open space for swimming. The front part of these fins are soft and perfect for precise positions and effortless movements in the water as opposed to fast swimming. The wide variation within the species as recognized by Willis et al. Biotropica, 12(2):144-157. CABI, Undated. Shafland PL, 1995. Biological Invasions, 11(8):1789-1801. http://www.springerlink.com/content/y036321605317279/fulltext.html, Robins RH, 2015. However, natural dispersal of C. ocellaris may be constrained by salinity and temperature tolerances. The Peacock Cichlid is not a very good choice for most aquarists because they will require a very large aquarium and quite frequent water changes. Annual growth estimates for the species in the Tamiami Canal over the years 1-6 were calculated as 204 mm, 327 mm, 418 mm, 480 mm, 531 mm and 592 mm (Shafland, 1999c). http://www.fishbase.org. Like a typical cichlid, they probably would not tolerate another male unless kept in a very large tank. contact Once the eggs have hatched, the parents transport the larvae in their mouths to a shallow depression in the sediment, or “nest” (Zaret, 1980). Ichthyological Explorations of Freshwaters, 17(4):289-398. The reduction in the planktivore Melaniris chagresi (Atherinidae) resulted in a reduction in tertiary-consumer populations including tarpon, black terns, kingfishers and herons in addition to changes within the zooplankton community. Dams and the fish fauna of the Neotropical region: impacts and management related to diversity and fisheries. Fish information on the Lake Malawi Cichlids known as the "Haps", Haplochromis group habitats and cichlids tanks for free-swimming types of cichlids, including the Utaka. The range of C. ocellaris in Florida is limited by cold winters that restricts it to the southernmost counties and exclude it from much of the Everglades (USGS NAS, 2015). This species has also established in Wahiawa Reservoir, a 350-acre, privately owned irrigation reservoir on Oahu (USGS NAS, 2015). The second part of the dorsal has white spots, and those spots are also found on the top part of the tail fin. This species is not listed on the IUCN Red List.

Wallingford, UK: CABI, CABI, Undated a. CABI Compendium: Status as determined by CABI editor. Reservoirs in the Upper Paraná River, São Francisco River and Northeast are massively invaded by, Reservoirs in the southeast and northeast Brazil are extensively invaded by, Hunting, angling, sport or racing (pathway cause), Espínola LA, Minte-Vera CV, Júlio Junior HF, Santos LN, Winemiller KO, 2015. C. ocellaris has been widely dispersed, for example, in the USA, as a sport-fish and there is the potential for this to continue (USGS NAS, 2015). Swingle HS, 1966. Exotic fishes in Hawaii and other islands of Oceania. Fish tank care. The frequency of water changes coupled with the large size of the aquarium means the owner will need to spend significant amounts of time maintaining this fish. They appreciate a bottom of sand or gravel with some rocks and wood for cover along with some flat stones for spawning. They live in large bodies of water, in the rapids as well as in quiet waters at a medium depth. It can be treated with the elevation of the tank temperature to 86° F (30° C) for 3 days. However, these fish did not survive the cold winter of 1964-1965 (Courtenay et al., 1974; Courtenay and Robins, 1989). Revista Brasileira de Biologia, 12:273-278. Introduction and establishment of a successful butterfly peacock fishery in southeast Florida canals. Upon introduction to favourable environments, populations of C. ocellaris may disperse rapidly through interconnected river systems and aquatic habitats.
