cichlid

(sĭk`lĭd), common name for members of the family Cichlidae, more that 1,600 species of spiny-finned freshwater fishes of moderate or small size, native to Africa, S Asia, Mexico, and Central and South America. Cichlids are found in tropical waters. The larger species are food fish of some importance (e.g., the tilapiatilapia
or St. Peter's fish,
a spiny-finned freshwater fish of the family Cichlidae, native chiefly to Africa and the Middle East. Fish of the genera Oreochromis, Sarotherodon, and Tilapia,

), and small, often very colorful species are popular as aquarium fish. Cichlids are noted for the care they give their young; the eggs are often laid in a basin hollowed in the sand and, the fertilized eggs or larvae are typically brooded in the mouth of either the male or the female, depending on the species. Cichlids are classified in the phylum ChordataChordata
, phylum of animals having a notochord, or dorsal stiffening rod, as the chief internal skeletal support at some stage of their development. Most chordates are vertebrates (animals with backbones), but the phylum also includes some small marine invertebrate animals.

Cichlid

(graphics, tool)
A tool for rapidly visualising arbitrary data in high-quality 3D, while allowing the viewer to explore and interact with the data in real time. Cichlid was designed with remote data generation and machine independence in mind; data is transmitted via TCP from any number of sources (data servers) to the visualisation code (the client), which displays them concurrently.

The overlap and spread of the Discriminant-Hotelling's test might have been the poor classification of the samples pertaining to sexes and that hermaphrodites shares very close sexual characteristics.With other perciformes, like Tropheus cichlid lineages, they exhibit distinguishable morphological characteristics with minor variation due a tightly packed community with limited capacity of dispersal [15] and this phenimenon might be the cause of the minimal variation between male and female of M.
