Water: Freshwater.
Temperature: 72–77°F (range recorded for this species).
pH: 6–8.
Hardness: 5–12 dGH.
Layout: Lives on or near the bottom: floor space and hiding places matter more than height.

Calculated from this species' own FishBase record: tank size from its typical adult length and swimming zone, water values from its recorded ranges. The group guide below fills in general care.

Care guide

Species care notes

Water: a fairly wide range, from slightly acidic to slightly alkaline, 72–79 °F, pH 5–7.5, 5–12 dGH.
Behaviour: in a pair.
Difficulty: Easy (Seriously Fish rating).

Short excerpts from the species profile:

Setup: “The tank should contain plenty of hiding places and potential spawning sites.”
Diet: “It will accept most foods offered but live and frozen varieties should form the bulk of the diet.”
Tankmates: “Recommended for the general community tank but do note that the fish become territorial when breeding.”

Group care guide

West, Central and southern African river cichlids and tilapias

Applies to most species in this group. Habitat: African rivers, streams and lakes. Individual species can differ, so compare with the species numbers above and the linked sources.

Housing & setup

Kribensis and other dwarf West Africans do well in planted 20–30 gallon tanks with caves and neutral water.
Tilapias and Serranochromis grow large and are often kept in ponds or for aquaculture.

What this means for care

Keep water within its wild range, 72–77 °F.

FishBase species summary: Pelvicachromis taeniatus

Native climate (measured)

Warm-season highs	about 91°F (up to 102°F in the hottest sampled areas)
Cool-season lows	about 70°F (down to 63°F in the coldest sampled areas)
Average temperature	77–83°F across sampled records
Relative humidity	77–85% on average (driest month about 77%)

Federal legal snapshot

No federal permit to keep

No federal law singles out this species for private keepers. State and local rules still apply.

State law decides most of it. Each state sets its own permits and bans for exotic, native, venomous and dangerous animals, and cities and counties can be stricter. Find your state agency →

Not covered by the Animal Welfare Act

The Act only covers warm-blooded animals. Reptiles, amphibians, fish and invertebrates have no federal care standards, even at licensed facilities; state and local rules may still apply.
