Can Cherry Spot Rasbora and Wami Tilapia (Redeye) Live Together?

Cherry Spot Rasbora is a peaceful species (1/10), while Wami Tilapia (Redeye) is moderately assertive (6/10). This notable difference means Wami Tilapia (Redeye) may occasionally assert dominance over Cherry Spot Rasbora.

Cherry Spot Rasbora and Wami Tilapia (Redeye) both frequent the Middle (Open Water) region of the setup. This overlap can increase competition for space, so providing ample room and cover is important to keep both species comfortable.

Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion. Aggressive eaters may outcompete shy fish for food, leading to malnutrition.

To improve the chances of a peaceful coexistence in this community tank: Provide a significantly larger tank (at least 50% more volume than the minimum) to allow both Cherry Spot Rasbora and Wami Tilapia (Redeye) to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations. A larger aquarium with ample hiding spots can help diffuse aggression and give the less dominant fish space to retreat.

The safe temperature window for both species falls between 23°C and 28°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.

Both fish can tolerate a pH between 6.5 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 5–12 dGH. Regular testing will ensure conditions stay within this range.

To house Cherry Spot Rasbora and Wami Tilapia (Redeye) together, plan for an aquarium of at least 280 litres with a minimum length of 120 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.

Specific environmental needs for this combination include: Plants - Densely covered, Plants - Floating, Sand (Sifters). Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Wami Tilapia (Redeye) is a plant destroyer, which conflicts with Cherry Spot Rasbora's requirement for live plants. Compromise where possible or prioritise the more critical need.

Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.

This pairing usually fails when the tank is treated like a standard mixed community and the caution flags are ignored. Cherry Spot Rasbora and Wami Tilapia (Redeye) need extra room, more cover, and closer observation during the first few weeks so small aggression, feeding, or territory issues do not snowball into a long-term problem.

Feeding time deserves special attention with this pairing. Wami Tilapia (Redeye) is an aggressive eater that may prevent Cherry Spot Rasbora from getting enough food.

Because Wami Tilapia (Redeye) is a fast, competitive feeder, consider using sinking pellets or feeding at opposite ends of the setup to ensure Cherry Spot Rasbora receives an adequate share.
