Calvus Cichlid Tank Setup
Plan for at least 40 US gal min of water—that is the minimum in our database for a workable setup, not a challenge to crowd fish. Aim to hold 75–81°F and pH 7.5–9 without daily drama. These fish use the Mid/Bottom zone most, so put wood, plants, or open water there accordingly.
What Do Calvus Cichlids Eat?
We record diet as Carnivore (micro/live foods). Offer a few food types that match—dry, frozen, or gel—and swap now and then. One flake every day for a year is how dull color and gut trouble creep in.
Calvus Cichlid Tank Mates
Temperament in the data: Aggressive. Treat small tank mates as potential snacks once the fish grows. Lake Tanganyika predator; very slow-growing. Ambushes small fish and fry. Laterally compressed body. Plug your full stock list into the stocking calculator—single-species compatibility scores are hints, not a whole-tank verdict.
Are Calvus Cichlids Good for Beginners?
We rate this as intermediate. Budget time for testing, maintenance, and watching behaviour if the water looks fine but the fish do not. If this would be your very first tank, start with something more forgiving and come back to this one.
