Looks how to spot one

Bottom-dwelling rapids cichlid

A sturdy, elongated cichlid with a big rounded forehead hump that is most impressive in adult males.2 3

Coloursmuted, understated tones2

Personality what they are like

Territorial and pair-oriented; settles best with non-cichlid tankmates.2

Daily activity how busy a day looks

Hops along the bottom in short bursts instead of swimming in open water.2

Grooming and care the hands-on bits

Provide strong flow and good oxygenation in parts of the tank, with quieter corners, plus caves made from rocks.2 3

Home where they are happiest

Tropical water of about 24 to 28 C, pH roughly 6 to 8 and 2-19 dGH, in a tank with a base of at least 75 x 30 cm (FishBase suggests 80 cm for a pair).2 1

Food basics what goes in the bowl

Feeds a lot on algae in the wild; offer quality pellets or flakes plus live or frozen bloodworm and brine shrimp.1 2

Company who they like around

Keep as a pair; good with tetras, plecos and catfish, and other cichlids only in a very large tank.2 1

The story where it all began

Poll described the species in 1939 from Pool Malebo and the lower Congo River. It is a rapids specialist that is also found in the aquarium trade.1 3

Fun facts for the dinner table

1
Its swim bladder is reduced, so it hops along the bottom instead of hovering in midwater.2
2
The forehead hump can change size quite quickly.2
3
It lives in fast-flowing rapids, which makes it a rheophilic fish.3
4
Both parents guard their young for up to three months.2

Recognised by the official bits
