Behaviour & Temperament

Bleeding Heart Tetra is a peaceful species (2/10), while Fosso Cichlid (Fossorochromis rostratus) is moderately assertive (6/10). This notable difference means Fosso Cichlid (Fossorochromis rostratus) may occasionally assert dominance over Bleeding Heart Tetra.

Bleeding Heart Tetra and Fosso Cichlid (Fossorochromis rostratus) 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.

Water Parameters

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 Fosso Cichlid (Fossorochromis rostratus) (7.8–8.6) 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.

Tank Setup

To house Bleeding Heart Tetra and Fosso Cichlid (Fossorochromis rostratus) together, plan for an aquarium of at least 680 litres with a minimum length of 180 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, Driftwood (Digestion/Hiding), Leaf Litter/Blackwater, Sand (Sifters). 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.

Why This Pairing Usually Fails in Practice

Bleeding Heart Tetra and Fosso Cichlid (Fossorochromis rostratus) 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.

Suitable Tank Sizes

Standard aquarium sizes large enough for both Bleeding Heart Tetra and Fosso Cichlid (Fossorochromis rostratus).

Frequently Asked Questions

Can Bleeding Heart Tetra and Fosso Cichlid (Fossorochromis rostratus) live together?

No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.

What size tank do Bleeding Heart Tetra and Fosso Cichlid (Fossorochromis rostratus) need?

A minimum of 680 litres (tank length at least 180 cm) is recommended. This provides enough space for both species to establish their own areas and reduces the likelihood of territorial disputes.

What water temperature is best for Bleeding Heart Tetra and Fosso Cichlid (Fossorochromis rostratus) together?

Keep the aquarium between 24°C and 28°C. A target of around 26.0°C sits comfortably within both species' preferred ranges.

Are Bleeding Heart Tetra or Fosso Cichlid (Fossorochromis rostratus) aggressive?

Bleeding Heart Tetra is peaceful (2/10) and Fosso Cichlid (Fossorochromis rostratus) is moderately assertive (6/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Bleeding Heart Tetra and Fosso Cichlid (Fossorochromis rostratus) need?

Their pH requirements do not overlap. Bleeding Heart Tetra prefers 5.5–7.2, while Fosso Cichlid (Fossorochromis rostratus) needs 7.8–8.6. This makes them incompatible in the same water chemistry.

Will Bleeding Heart Tetra nip Fosso Cichlid (Fossorochromis rostratus)'s fins?

Bleeding Heart Tetra is a known fin nipper. If Fosso Cichlid (Fossorochromis rostratus) has long or flowing fins, there is a real risk of fin damage. Keeping Bleeding Heart Tetra in a larger group can help redirect nipping behaviour toward conspecifics.

How do I manage Fosso Cichlid (Fossorochromis rostratus)'s territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Fosso Cichlid (Fossorochromis rostratus) space to claim a territory without encroaching on the other fish's area. Adding décor that divides the tank into distinct zones works especially well.
