The pearly calvus (Altolamprologus calvus) is a Lake Tanganyika cichlid built like a blade — extremely compressed side to side, with heavy scaling and a sloping head that lets it push into narrow rock cracks after prey. It hangs almost motionless in the water, then moves suddenly. Growth is famously slow, so a small fish stays small for a long time, and patience is part of keeping one.
Aquarium care
- Adults can reach 12 to 13 cm, but take years to get there.
- Needs hard, alkaline water and stacked rockwork with narrow crevices.
- A predator of small fish, fry and shrimp — anything that fits in the mouth is food.
- Calm and unaggressive toward fish too large to eat.
- Takes quality pellets and frozen foods; feed with restraint given the slow growth.
- Spawns in shells and tight crevices.
Good in a Tanganyikan community with other rock dwellers of similar or larger size. Do not keep it with small fish, dwarf shrimp or anything else it can swallow. It is a poor match for a soft-water community tank.
Stock rotates with each shipment, and livestock is available for local pickup at our Lethbridge store. See the Tanganyikan collection.
