Can Bleeding Heart Tetra and Yellow Lab (Mbuna) Live Together?

Bleeding Heart Tetra is a peaceful species (2/10), while Yellow Lab (Mbuna) is moderately assertive (6/10). This notable difference means Yellow Lab (Mbuna) may occasionally assert dominance over Bleeding Heart Tetra.

Bleeding Heart Tetra and Yellow Lab (Mbuna) 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.

The safe temperature window for both species falls between 24°C and 28°C. Aim for the midpoint of this range (around 26.0°C) for optimal comfort.

The pH requirements of Bleeding Heart Tetra (5.5–7.2) and Yellow Lab (Mbuna) (7.5–8.8) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–15 dGH. Regular testing will ensure conditions stay within this range. An aquarium test kit is recommended for monitoring.

To house Bleeding Heart Tetra and Yellow Lab (Mbuna) together, plan for an aquarium of at least 180 litres with a minimum length of 90 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.

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, Driftwood (Digestion/Hiding), Leaf Litter/Blackwater, Sand (Sifters), Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Yellow Lab (Mbuna) is a plant destroyer, which conflicts with Bleeding Heart Tetra's requirement for live plants. Compromise where possible or prioritise the more critical need.

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