Can Lake Tebera Rainbowfish and Three-striped Dwarf Cichlid Live Together?

Lake Tebera Rainbowfish is a peaceful species (2/10), while Three-striped Dwarf Cichlid is generally mild-mannered (4/10). This modest difference means Three-striped Dwarf Cichlid may occasionally assert dominance over Lake Tebera Rainbowfish.

Lake Tebera Rainbowfish and Three-striped Dwarf Cichlid 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.

Worth noting: Lake Tebera Rainbowfish is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 24°C and 25°C. Aim for the midpoint of this range (around 24.5°C) for optimal comfort.

The pH requirements of Lake Tebera Rainbowfish (7.2–8) and Three-striped Dwarf Cichlid (5–7) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 8–10 dGH. Regular testing will ensure conditions stay within this range.

To house Lake Tebera Rainbowfish and Three-striped Dwarf Cichlid together, plan for an aquarium of at least 110 litres with a minimum length of 90 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

Providing a mix of open swimming space and sheltered areas with rocks, driftwood, or plants will keep both species comfortable and allow natural behaviour.

Specific environmental needs for this combination include: Plants - Densely covered, Sand (Sifters), Leaf Litter/Blackwater, Driftwood (Digestion/Hiding). Meeting these requirements will help both species thrive.

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

Lake Tebera Rainbowfish and Three-striped Dwarf Cichlid are the kind of pair that can look acceptable in a shop but become a maintenance problem at home. The main risk is not a single number in the chart; it is the way incompatible behavior, water needs, or pressure on space compounds over time once both fish are established in the same tank.

Feeding time deserves special attention with this pairing. Lake Tebera Rainbowfish is an aggressive eater that may prevent Three-striped Dwarf Cichlid from getting enough food.

Because Lake Tebera Rainbowfish is a fast, competitive feeder, consider using sinking pellets or feeding at opposite ends of the setup to ensure Three-striped Dwarf Cichlid receives an adequate share.
