(sĭk`lĭd), common name for members of the family Cichlidae, several hundred 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, and small species are popular as aquarium fish. Cichlids are noted for the care they give their young; the eggs are laid in a basin hollowed in the sand and, until they hatch, are stored 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.

(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.
