Female

Slightly smaller and generally less aggressive than males. As maternal mouthbrooders, they will hold eggs and fry in their mouths. Can be kept in groups or as a harem for a single male.

Wami Tilapia (Redeye) Care Guide Summary

The Wami Tilapia (Redeye), scientifically known as Oreochromis hornorum, belongs to the Cichlids - African family group. Adults reach a maximum size of approximately 30 cm and have a compressed body shape with a fast growth rate. Classified as semi-aggressive, this species primarily occupies the mid-level and bottom zones of the aquarium and produces a extreme level of biological waste.

To thrive, the Wami Tilapia (Redeye) requires a brackish tolerant aquarium with a minimum volume of 280 litres and a tank length of at least 120 cm. Water temperature should be maintained between 22°C and 28°C, with a pH range of 6.58.5 and a general hardness of 525 dGH. A moderate water flow is preferred.

The Wami Tilapia (Redeye) is a rewarding species to keep, provided its core environmental needs are met. This species is available in 3 varieties: Male, Female, and Juvenile (Grow-out). Each may differ slightly in size, temperament, or care needs, so it is worth checking the specific requirements of the variety you plan to keep.

Wami Tilapia (Redeye) Habitat Setup

When setting up an aquarium for the Wami Tilapia (Redeye), a moderate water flow best suits their natural preferences. Because this species occupies the mid-level and bottom zones, the aquarium layout should prioritise open swimming space in the centre of the tank for free movement and sufficient floor space with hiding spots among rocks, wood, or dense planting. Useful additions include a sand substrate to accommodate their sifting behaviour. Keepers should note that expect substrate disturbance, so lightweight décor should be secured and live planted layouts may be difficult to maintain, as this species tends to uproot or consume vegetation.

Wami Tilapia (Redeye) Compatibility Notes

Classified as semi-aggressive, the Wami Tilapia (Redeye) is adaptable and can be kept singly or in a small group, offering flexibility when planning a community tank. When choosing tankmates, territorial behaviour may cause issues if hiding spots or floor space are limited, shy or slow-feeding tankmates may be outcompeted at feeding time, and their energetic swimming style may stress more sedentary or timid species. Selecting tankmates that favour different water layers from the mid-level and bottom zones can help reduce competition and territorial overlap.

Who Wami Tilapia (Redeye) Is Actually For

Wami Tilapia (Redeye) is best for a fishkeeper who wants a species that can settle into a calmer community setup and can provide someone who understands its individual space requirements. It makes the most sense for a hobbyist who will actually build around its needs, especially sand.

The most common mistake is treating Wami Tilapia (Redeye) like any other community fish and skipping the soft sand it needs to forage safely. Another frequent problem is forcing it into an over-busy community when it would do better with more room or more deliberate tankmate choices.

Wami Tilapia (Redeye) Feeding & Diet Considerations

The Wami Tilapia (Redeye) will eat fry, so breeding efforts in the same tank are unlikely to succeed and is an aggressive eater that may prevent timid tankmates from getting enough food, so target feeding or simultaneous feeding at opposite ends of the tank can help.
