Altolamprologus calvus 'Yellow'

Altolamprologus calvus 'Yellow' is a captive-selected colour form displaying warm golden-yellow to amber flanks with the characteristic compressed body and spot patterning of the species. While not a wild-type colour form, the Yellow Calvus has established itself firmly in the hobby and is maintained by specialist breeders.

Behaviourally and ecologically, this morph is identical to the black and white forms. It brings a distinctive warm colour palette to Tanganyika aquariums and contrasts beautifully with blue or black-bodied tankmates such as Cyphotilapia or dark Julidochromis morphs.

The Yellow Calvus is slightly less widely available than the black or white forms but is produced by a growing number of breeders. It requires no different care and offers the same behavioural interest — slow-growing, patient, cave-spawning, and endlessly fascinating to observe.

Water: 24–27°C, pH 7.8–9.0, GH 10–18, KH 8–16; high-quality alkaline water maintains yellow pigment intensity. Tank: 150 L minimum; rockwork with narrow hiding places; shells for potential spawning sites. Feeding: Small premium cichlid pellets; frozen Mysis, shrimp, and bloodworm; small daily feedings. Breeding: Cave/shell spawner; 50–150 eggs; female guards vigorously; fry grow slowly and need fine live foods initially. Compatibility: Peaceful with fish too large to eat; excellent in mixed Tanganyika communities.
