About 16 cm maximum length; most much smaller. Elongate pelvic fins, inserted before or behind pectoral fin base; with 1 spine and 5 soft rays 5. Require unrestricted space, hence unsuitable for home aquaria. The single dorsal fin originates on the head and extends over nearly the full length of the body. Colorful cichlids are reared as aquarium fish. A strong spine in preopercle. Caudal rays 15, branched. Gut coiled several times. Maximum length about 60 cm reported for Heterostichus rostratus; mostly well below this size (Ref. Vomer and palatine toothless. Trophic ecology: Fusiliers are closely related to snappers (Lutjanidae) but possess several adaptations for a planktivorous mode of life, such as the elongate fusiform body, the small mouth, and the deeply forked caudal fin. Mostly nest builders. 4. Snout fleshy and jutting beyond lower jaw. Dorsal spines 3-17, flexible; 9-119 segmented soft rays. The anal fin with 1 spine and 15 soft rays. Ectopterygoid no teeth. 7463. Scales ctenoid or cycloid. Interrupted lateral line in most species. 7463) needs to be reviewed after the splitting. 36343). The majority of the Neotropical cichlids feed on a variety of invertebrates and some plant matter, and specializations among those species remain little investigated. Dorsal fins far apart. Distribution: lowlands of the Ganges, Brahmaputra and Mahanadi basins, in Nepal, India, and Bangladesh; and, Irrawaddy in Myanmar and China (Dario species). All have been assigned to Datnioides, now the genus type for the family. The single dorsal fin originates on the head and extends over nearly the full length of the body. 7463). Eggs are typically deposited on a substrate and both parents guard offspring over several weeks, even for some time after the young are free-swimming. Spines in dorsal fin 10; soft rays usually 18-23. Moderately elongate and compressed fishes with small mouths and thick lips. Members of Cepolinae are notably elongate, 48-79 total vertebrae and 55-90 total dorsal-fin soft rays, with the terminal dorsal- and anal-fin soft rays attached to the caudal fin by a membrane (Ref. Gill membranes fused. It was mistakenly reported that Anguillidae lack a scapular bone after further research and more advanced staining techniques they have a scapula and coracoid which make up their pectoral girdle. Rounded caudal fin. Anterior dorsal fin with 4 or 5 spines; the second dorsal fin with 1 short spine and about 18 or 19 soft rays.

Suggested new common name for this family from Ref. Bussing (1998: 293-384) summarizes data on 24 Costa Rican cichlid species; Keith et al. Attain total lengths of 31-127 cm. Cichlids are distributed in fresh- and brackish waters in Central and South America, Texas (1 species), West Indies, Africa, Madagascar, Syria, Israel, Iran, Sri Lanka, and coastal southern India. Only one species occurs in true marine waters Tilapia guineensis (Günther, 1862). Maximum length about 1.4 m. All have been assigned to Datnioides, now the genus type for the family. Benthic, making extensive systems of tunnels with numerous exits by burrowing in soft substrates. Long anal fin with a single spine. Relatively deep-bodied. Worldwide. Benthic, making extensive systems of tunnels with numerous exits by burrowing in soft substrates. Mouth strongly oblique. 7463); especially diverse in South African and southern Australian waters (Ref. No cirri on nape, may be present elsewhere on head. = tooth Palatines toothless. 119093). Some species are widely introduced. The stomach has a left hand exit to the anterior intestine and the first intestinal loop is on the left side (Zihler, 1982) Deep bodied.

Centrogenyidae - (False scorpionfishes) Dorsal fin extending over length of body in some; anterior dorsal fin spines unbranched; anal spines lost; 36-54 vertebrae. One lateral line; snout not produced. Morphology: Continuous dorsal fin with 0-4 spines (often 3). 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. Most of these are now recognized in well-diagnosed genera (Kullander, 1986, 1996, Kullander & Hartel, 1997), but several are kept with the generic denomination ‘Cichlasoma’ which is judged better than to include them in genera to which they certainly do not belong. Suggested new common name for this family from Ref. 58418. Body color usually red or pink. Also Ref. Primarily demersal, inhabiting shallow to moderately deep cold waters. Chironemidae - (Kelpfishes) To about 50 cm maximum length. Chaetobranchopsis, Chaetobranchus and Satanoperca acuticeps are plankton feeders.

A few mouthbrooding species practice exclusive maternal brood care, with a minimum delay between egg-laying and oral incubation (Gymnogeophagus balzanii, NE Colombian Geophagus species). Most dwell in abandoned invertebrate tubes and feed on small crustaceans. Propensity to occur in algae and seagrass areas (Ref. Distribution: North and South America. Dorsal fin long, continuous or divided; 7-23 spines, 12-36 soft rays. Three spines in anal fin, soft rays usually 13 or 14. Geographical ranges are commonly limited to a single river or even one or a few streams, reflecting both ecological constraints and drainage basin histories. The traditionally most important aquarium species are Pterophyllum and Symphysodon species, the former often representing the aquarium hobby in logotypes. Vertebrae often 28-44 (135 in Xiphasia) (Ref. 119093). Dorsal and anal fin bases long. Juveniles enter fresh water in spring and spend the rest of their lives there. The check-list herein recognizes 403 valid Neotropical cichlid species out of XXX nominal taxa. Datnioididae - (Freshwater tripletails) Cephalic mechanosensory canals not opening to the outside. Palatine and vomerine teeth present.

The sagitta features an anterocaudal pseudocolliculum having a long and thick ventral part which is separated from the crista inferior by a long, deep and sharp furrow (Gaemers, 1985). Deep bodied. To 85 cm maximum length, reported for Taractichthys longipinnis. Oceanic. Deeply forked caudal fin. Fluctuating oceanic conditions associated with climate change also make these species vulnerable, with reduced water quality leading to biodiversity loss among the largest threats. Datnioididae - (Freshwater tripletails) This implies: Caudal rays 15, branched. Paracaristiinae ((Paracaristius, Neocaristius): small mouth, end of maxillary bone hardly extends beyond vertical through middle of eye; upper jaw totally covered by suborbitalia; wide suborbital region (width 9.5-14.5% SL); About 1.2 m maximum length.

Premaxilla and maxilla elongate and slender, firmly fused distally. 94114). Have many features in common with the scorpaenids. Some root in sand for invertebrates and fishes. are placed in a new family, Latidae (= former Centropomidae: Latinae) (Ref. Distribution: tropical western and eastern Atlantic, Indian and Pacific (mainly Indo-Pacific). 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. Distribution: tropical and subtropical eastern North and South America, Africa, Asia, Kermadec Islands, and Hawaii. 94100).

Many feed on a combination of coelenterate polyps or tentacles, small invertebrates, fish eggs, and filamentous algae while others are specialists or planktivores.
