Etymology: Pelvicachromis: Latin, pelvica, -ae = bassin + Greek, chromis = a fish, perhaps a perch (Ref. 45335); sacrimontis: Sacri from Latin sacer, meaning holy, and montis from Latin mons/montis meaning mountain; in total the name serves as a Latin translation for Heiligenberg, a German biologist cited by Paulo in his descriptionof the species (Ref. 119364).
Eponymy: Walter Heiligenberg (1938–1994) was a German American neuroethologist who specialised in the motivational behaviours of cichlids and crickets. [...] (Ref. 128868), visit book page.

Краткое описание
определительные ключи | морфология | морфометрия
колючие лучи спинного плавника (общее число) : 15 - 17; членистые (мягкие) лучи спинного плавника (общее число) : 8 - 10; колючие лучи анального плавника: 3; членистые (мягкие) лучи анального плавника: 6 - 8; позвонки: 26 - 27. Diagnosis: It is a species of Pelvicachromis, distinguished from all congeners by a combination of characters as follows: it differs from Pelvicachromis taeniatus and P. subocellatus in absence of a pattern of pale blue and reddish dots on the caudal fin of adult males; it differs from P. roloffi in a broader midlateral band on the body, absence of small dots in the male caudal fin, absence of red margin with whitish to bluish submargin in the female dorsal fin; it differs from P. humilis, P. rubrolabiatus and P. signatus in absence of dark vertical bars on body; it differs from P. pulcher in a broader midlateral band on the body, usually as broad or broader than a pale yellowish band dorsal to this dark band, iridescent blueish to turquoise colouration band on cheeks and a different colouration of the dorsal fin in females; no margin, spiny portion pale to dark and dusky orange, soft parts yellowish to clear in most posterior regions vs. black margin, yellow submargin and black fin base in P. pulcher (Ref. 119364).
In aquaria, this species is a monogamous, pair bonding cave-spawner (Ref. 119364).
Life cycle and mating behavior
половая зрелость | размножение | нерест | икра | Fecundity | личинки
In aquaria, this species is a monogamous, pair bonding cave-spawner (Ref. 119364). Eggs are guarded by both sexes, but always more intensively and more often by the female; hatching occurs after three days post-spawn; larvae are usually deposited on the bottom of the cave, rarely in other caves nearby the original cave; juveniles are free swimming eight or nine days post-hatching and guarded by both parents for about five to six weeks; breeding and guarding individuals of both sexes regularly exhibit a more prominent midlateral black stripe (Ref. 119364).
