Anal fin soft rays 4-10. Much of Pellegrin’s efforts with the Neotropical taxa were improved upon by Regan’s series of generic revisions in the next two years (Regan, 1905-1906), which remained the platform for all Neotropical cichlid systematics until the 1980s.

Another early major treatise is by Jardine (1843), based on the Schomburgk collection from Guyana, Brazil and Venezuela (Kullander & Stawikowski, 1997a-b, for identifications). Cichlid diversity has been explained both by their advanced brood care and by the versatile design of the pharyngeal jaw complex used for food mastication. 8.

There is no scientific monograph covering all Neotropical cichlid species, but numerous aquarium books of variable quality, of which Stawikowski & Werner (1998) may be consulted for the most updated compilation of cichlasomine cichlids. Bussing (1998: 293-384) summarizes data on 24 Costa Rican cichlid species; Keith et al. Their tail makes a D-shape when viewed from the side. Most Atlantic coastal rivers of Brazil have 1-3 species of cichlids. Slender fishes with compressed head and body. 7463).

Among Neotropical taxa, lengths range from about 25-30 mm adult size in Apistogramma and Taeniacara, to about 1 meter in Cichla temensis. Primarily Indo-west Pacific. Most taxa are in the interval 10-20 cm, however. Chaetodontidae - (Butterflyfishes) The oral jaws are generally highly movable and protrusible, and tooth shape varies greatly, although most Neotropical cichlids have simple, subconical, unicuspid teeth, whereas African cichlids commonly have laterally bicuspid or tricuspid oral teeth. The current estimate of 450 South American taxa is based on species already represented in museum collections; it can be assumed that new collections will bring in many more new taxa. Eggs are demersal and adhesive (Ref. 9850). Dichistiidae - (Galjoen fishes) Chaetodontidae - (Butterflyfishes) Suggested new common name for this family from Ref. Primarily Indo-west Pacific.

Most Neotropical Cichlidae are moderately to strongly sex dimorphic, and breed pairwise. The subterminal mouth is very effective for grazing invertebrates from rock surfaces. Now that I’ve passed on everything I know about the colors and patterns of bettas, it’s time to talk about their fins.Those fancy tails are one of the key features that draw people to these magnificent fish.

Hide in holes at night (Ref. Most Atlantic coastal rivers of Brazil have 1-3 species of cichlids. Cichlidae - (Cichlids) Mouth nonprotrusible. Distribution: Antarctic.
