Overview
The blackchin sand diver is a gentle Tanganyikan cichlid that spends its whole life in shoals over the open floor. It is a fish for experienced keepers.
Did you know
At spawning time, male blackchin sand divers gather in one place and display side by side. This display ground is called a lek, and the females move through it to choose a mate.
Caring for the blackchin sand diver
A proper school needs floor space, so give blackchin sand divers at least 106 gal (400 L) with a long footprint. Lay a broad, deep bed of soft, fine sand with open water and little or no rock. That lets the school move and gives the males room for their nests.
Keep the water hard, alkaline and spotlessly clean, at 75 to 81°F (24 to 27°C) and a pH of 7.8 to 9.0. Feed small foods often, such as fine sinking pellets, frozen cyclops, mysis and brine shrimp.
It is a true schooling fish, so plan on a group of at least eight to a dozen. A lone fish or a tiny group frets and does poorly. It is peaceful and easily stressed, so skip rough or boisterous tank mates altogether. A species tank is often the best choice.
Males build crater-shaped nests in the sand at spawning time, and the females are maternal mouthbrooders that carry the eggs and fry. Breeding it is hard.
Good to know
The blackchin sand diver is a member of the cichlid family. For many years it was known as Enantiopus melanogenys, before it moved to the genus Xenotilapia.
In the wild
In Lake Tanganyika, the blackchin sand diver forages over open sand, picking small invertebrates from the substrate.
