Etymology: Copadichromis: Greek, kopas, -ados = carved + Chromis, see; ilesi: Named in honor of T.D. Iles, for his work on the 'Utaka' of Lake Malawi (Ref. 47113).
Eponymy: Thomas Derrick Iles (1927–2017) was a British fishery biologist and ichthyologist. [...] (Ref. 128868), visit book page.

生態学
; 新鮮な水 底生の漂泳性; 深さの範囲 7 - 30 m (Ref. 47113), usually ? - 15 m (Ref. 47113). Tropical
Africa: Lake Malawi.
サイズ / 重さ / 年齢
Maturity: Lm ? range ? - ? cm
Max length : 11.4 cm SL オス/雌雄の選別がない; (Ref. 47113); 11.1 cm SL (female)
背面の脊椎 (合計) : 16 - 17; 背鰭 (合計) : 10 - 12; 肛門の骨: 3; 臀鰭: 10 - 11. Depth of body 2.6-2.9 times in SL; head length 3.1-3.4 times in SL (Ref. 47113). Eye diameter 2.9-3.2 times in HL; interorbital width 3.4-4.1 times in HL; premaxillary pedicel 2.4-3.1 times in HL and depth of preorbital 5.6-7.0 in HL (Ref. 47113). Teeth in 2 to 3 rows in upper and 3 to 4 rows in lower jaw (Ref. 47113). Males mostly with unicuspid teeth in all rows; in females outer rows contain unequally bicuspid and inner rows contain unequally tricuspid teeth (Ref. 47113). Length of pectoral fin 2.8-3.7 times in SL (Ref. 47113). Caudal peduncle 5.4-7.6 times in SL; peduncle depth 1.0-1.5 times in its length (Ref. 47113). Scales: 34-35 scales in a longitudinal series (Ref. 47113). Without spots on the flanks (Ref. 47113). Geographical variation seems to be restricted to the color of the blaze on the male's head and dorsal fin (Ref. 47113).
Associated with rocks (Ref. 54524). Males build their spawning sites at depths of approximately 25 meters or deeper; females, in particular mouth brooding females, can be found in shallower water, but they rarely venture into regions shallower than 10 meters (Ref. 47113).
Life cycle and mating behavior
成熟 | 繁殖 | 放精 | 卵 | 生産力 | 幼生
The spawning site usually is constructed under and against a rock or small group of rocks; the male excavates the sand from beneath the rock and heaps it up, building a semicircular wall around the spawning site, sometimes leaving just a narrow opening to the nest (Ref. 47113). The spawning sites are usually about 2 meters apart (Ref. 47113).
