Tropheus polli is a type of cichlid fish found only in Lake Tanganyika’s central eastern coast, living in rocky areas. It’s sometimes sold in the aquarium trade.
The name “polli” honors Max Poll, an ichthyologist (fish scientist).
Some experts think this fish is the same species as Tropheus annectens.
Tropheus polli lives among rocks and stones near the shore of Lake Tanganyika and usually stays within a small area (about 20 to 23 feet) even when chased.
It’s found at depths of 20 to 33 feet, eating algae and other organisms on rocks.
For keeping this fish in an aquarium, it’s best to have multiple females for one male with a tank that is at least five feet long.
