The deepest lake in Africa. Hard, crystal-clear water. Cichlids with unique behaviors: shell dwellers, cleaner cichlids, and Frontosas.
Description
Lake Tanganyika is the second-deepest lake in the world. Its waters are exceptionally clear and mineral-rich. Unlike Lake Malawi, Lake Tanganyika has a much greater biodiversity of ecological niches: rock-dwelling cichlids, sand-dwelling cichlids, shell-dwelling cichlids, and large pelagic fish.

Authentic Decor
- Substrate: Fine white sand + Neothauma shells (or similar land snail shells) for shell dwellers
- Rocks: Flat piles of lake rocks forming horizontal and vertical labyrinths
- No trees, no plants (pure rocky area)
- For the shell zone: Flat sandy bottom with scattered shells, few rocks
Characteristics of the Tanganyika
- The spines of Tanganyika cichlids are more important than their colors in determining their well-being
- Shell dwellers need MORE shells than fish (a minimum ratio of 3:1)
- Tropheus are extremely territorial—they need groups of at least 12–15 to spread out their aggression
- Frontosa: very slow; needs fish that are too large to be eaten; requires a very deep aquarium
