Etymology: Haplochromis:Greek, Haploos = single + Greek, chromis = a fish, perhaps a perch (Ref. 45335); fischeri:Named for G.A. Fischer, one the first Europeans with a deep interest in natural sciences to visit the area, assembling vast collections of plants, animals and other natural objects and undertaking fundamental studies to produce accurate maps (Ref. 79882). Eponymy: Dr Gustav Adolf Fischer (1848–1886) was a German physician, naturalist and explorer of East and Central Africa. [...] (Ref. 128868), visit book page.
Umwelt: Milieu / Klimazone / Tiefenbereich / Verbreitungsgebiet Ökologie
Rückenflossenstacheln (insgesamt) : 15 - 16; Rückenflossenweichstrahlen (insgesamt) : 8 - 10; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 7 - 10; Wirbelzahl: 29. Diagnosis: relatively small species, moderately elongate (body depth 2.6-3.0 times in SL); dorsal head profile relatively steep, strongly convex dorsally of large eye (eye diameter about 4.0 times in HL, 1.2 times in snout length and 0.96 times in interorbital space); lips moderately but more or less equally thickened; outer teeth strong with recurved tips, procumbent, especially in lower jaw; usually anteriorly 3-6 rows of inner teeth in upper jaw, rows not very distinct; haplochromine "head mask" very weakly developed, hardly visible in not sexually active males; dominant males bluish with greenish hue; prominent dark grey longitudinal band from eye to caudal peduncle, interrupted above anterior half of anal fin; second dark grey longitudinal band along upper lateral line; 6-8 weakly expressed vertical bars about width of iris may be present in live and preserved fish (Ref. 79882).
Body shape (shape guide): fusiform / normal.
Found over sandy substrate, interspersed with patches of shelter which can be rocks or vegetation; especially common over exposed sandy beaches; feeds on gastropods, insect larvae, diatoms and copepoda (Ref. 79882).
Phylogenetischer Diversitätsindex (Ref. 82804): PD50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.00671 - 0.03113), b=2.99 (2.82 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophische Ebene (Ref. 69278): 3.4 ±0.4 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).
Anfälligkeit der Fischerei (Ref. 59153): Low vulnerability (10 of 100). 🛈
