About this species
General notes for hobby use.
Intentional catch-all for Acei-like hybrids of unresolved parentage. Keep the hybrid label explicit rather than assigning a pure species from colour alone.

Often more social/open-water than typical mbuna, but hybrid temperament is variable. A long tank and group structure reduce pressure on weaker fish.

Alternative names
Yellow Tail Acei Hybrid, Acei-type Hybrid, Pseudotropheus hybrid
Native range
Captive aquarium hybrid; no reliable natural locality can be assigned.
Natural habitat
Use an Acei/Malawi-style hard alkaline aquarium with open swimming room, sand and strong wood/rock structure.
Diet & feeding
Use a plant/algae-rich mbuna diet as the safe baseline, with modest supplemental animal protein.
Breeding & sexing
Research-backed guidance for identifying sexes and reproductive behaviour.
Sexing
Sexual differences depend on parentage; males are often larger/more colourful but visual sexing is not reliably diagnostic.
Breeding
Acei-type hybrids are expected to mouthbrood, but exact reproductive details vary with parentage. Do not present a pure-species breeding claim.
