Etymology: Rubricatochromis: Name from rubricatus, Latin for red coloured, refers to the bright red colouration on body of most species when in dominance or broodcare; and chromis, a common ending for African cichlid fishes (Ref. 128620); guttatus: From the Latin guttatus, meaning 'speckled', apparently referring to the pattern of black dots in the cheek and opercular region of the type material (Ref. 43352).
More on author: Günther.

Taxonomic Remarks
According to Loiselle (1979; Ref. 43352) this species would be the true "jewel cichlid" of aquariologists, also used as an experimental animal by physiologists and ethologists and commonly named H. bimaculatus (Ref. 5644).

Biologie     Verklarende woordenlijst (bv. epibenthic)

Eurytopic; found most frequently in association with stands of emergent or submerged aquatic plants; particularly abundant in shallower and quieter stretches of large rivers, in small lateral tributaries of such streams, in oxbow lakes and in swampy habitats; even maintains breeding populations in coastal lagoons; absent from rapids zone of streams or in headwaters flowing through montane forest (Ref. 43352). Forest-associated species (Ref. 43352, 52307). Pair-bonding, substrate brooders (Ref. 52307, 81260). Aquarium keeping: aggressive species, requires sufficient space to build territories; omnivore; spawns up to 300 eggs which hatch after 2 days, young are free-swimming after 5 days (Ref. 57572).

Levenscyclus en paargedrag Maturiteit | Voortplanting | Paaien | Eieren | Fecunditeit | Larven

Reported to form pairs. Female deposits eggs on exposed hard surfaces such as stones or wood. Both parents guard larvae and juveniles for about 4 weeks (Ref. 59043).
