Given their territorial nature, Wolf Cichlids require a spacious tank of at least 200 gallons to thrive. They are known for their intelligence and can easily bond with their owners.

To accommodate the Black Ghost Knifefish’s timid nature, it’s important to provide them with hiding spots in the tank.
