Aquarium Setup Julidochromis Regani
Aquarium Filtration
Strong filtration is essential to maintain excellent water clarity and stable parameters. Canister filters or sponge filters with biological media are ideal.
Aquarium Plants
Use hardy species such as Anubias or Java Fern attached to rocks, as rooted plants may be dislodged by territorial digging.
Aquarium Lighting
Moderate lighting highlights the fish’s intricate banding while minimising stress.
Aquarium Heating
Maintain consistent temperatures of 25–26°C with a reliable heater and thermometer.
Aquarium Substrate
Fine sand or smooth gravel is preferred, allowing for natural behaviour and minimal injury.
Aquarium Decorations
Construct extensive rock formations with caves and crevices to provide secure territories, replicating their native rocky environment along Lake Tanganyika’s shores.
