簡単な記述 形態学 | 形態計測学

背面の脊椎 (合計): 13 - 16; 背鰭 (合計): 10-14; 肛門の骨 3; 臀鰭: 8 - 10. Diagnosis: upper profile of head not convex; lower pharyngeal bone about as long as broad, and with anterior lamella shorter than toothed area; median pharyngeal teeth not broadened; dorsal fin with 14-16 spines and 10-14 soft rays (mean 15, 12); 8-11 lower gillrakers; dark longitudinal band appears on flanks when agitated; no bifurcated dark vertical bars on flanks; dorsal and caudal fins not or feebly blotched (Ref. 53405). Body brownish-olivaceous with an iridescent blue sheen; lips bright green (Ref. 34290, 53405). Chest pinkish (Ref. 34290). Dorsal, caudal and anal fins brownish-olivaceous with yellow spots, dorsal and anal fins outlined by narrow orange band; "tilapian" spot large, extending from last spine to 4th soft ray and always bordered by yellow band (Ref. 34290, 53405). Specimens 2-14 cm SL with completely yellowish or greyish caudal fin without dots, but tend to develop a greyish caudal fin with dots of increasing size during development; above 14 cm SL, this species has greyish caudal fins with dots on entire caudal fin (Ref. 57660).

生物学     用語集 (例 epibenthic)

Highly adaptable and tolerates varying water qualities; can be found across a wide range of temperatures and salinities, even surviving marine conditions (Ref. 52307). Occasionally form schools; mainly diurnal. Prefer shallow, vegetated areas (Ref. 4967). Fry are common in marginal vegetation and juveniles are found in the seasonal floodplain. Herbivorous (Ref. 52307), feed on water plants and epiphyton, and some invertebrates. Substrate spawner (Ref. 28714, 52307). Parental care is very thorough and undertaken by both parties; large specimens may deposit 1000 eggs per spawn, preferably on hard surfaces; hatching occurs about 96 hours post spawning, and juveniles swim freely about 4-6 days later (Ref. 52307). Larvae develop in close association with substrate. Extended temperature range 6.5 - 42.5 °C, natural temperature range 10.5 - 36°C (Ref. 3).

Life cycle and mating behavior 成熟 | 繁殖 | 放精 | | 生産力 | 幼生

Spawns in lake bottoms with pebbles or sand and abundant vegetation (Ref. 3). Lays adhesive eggs on the substratum which are guarded by both parents (Ref. 6298). Reported to deposit and guard eggs in shallow nest (Ref. 12069). Produces up to 1000 eggs (Ref. 1672).
