What to know before you buy.

Key traits
Care guide
Keeping Keyhole Cichlid healthy in a South African setup.
Tank setup
Size the aquarium to Keyhole Cichlid's adult size and activity level. Use robust décor and sight breaks so each fish can hold its own space.
Water parameters
Keep pH 6–7.5 and 22–27°C. Stable parameters matter more than chasing perfect numbers; acclimate new arrivals slowly.
Feeding
Omnivore. Feed small amounts it clears in a couple of minutes, and vary the diet.
Behaviour
Territorial. Watch it at feeding time and at lights-out to see its real temperament in your tank.
Tankmates
Choose robust tankmates of similar size, and nothing small enough to be eaten. Add Keyhole Cichlid last so territories reset.
Breeding
Breeding success with Keyhole Cichlid depends on the line and water chemistry; ask your shop about proven pairs.
Settling this fish in?
Condition the tap water, seed the filter, test through the first weeks — most early losses trace back to one of those.
