Can Lemon Cichlid (Leleupi) and Rose Danio Live Together?

Lemon Cichlid (Leleupi) is a semi-aggressive species (7/10), while Rose Danio is peaceful (1/10). This notable difference means Lemon Cichlid (Leleupi) may occasionally assert dominance over Rose Danio.

Large aggression gap (6 points) between Lemon Cichlid (Leleupi) and Rose Danio increases stress risk for the more peaceful fish.

Lemon Cichlid (Leleupi) and Rose Danio 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: Shrimp eaters may also prey on very small nano fish.

Worth noting: Rose Danio is a known jumper, so a tight-fitting lid is essential.

The safe temperature window for both species falls between 24°C and 26°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

The pH requirements of Lemon Cichlid (Leleupi) (8–9) and Rose Danio (6–7.5) 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.

To house Lemon Cichlid (Leleupi) and Rose Danio together, plan for an aquarium of at least 110 litres with a minimum length of 80 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: Sand (Sifters), Plants - Densely covered. 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.

Lemon Cichlid (Leleupi) and Rose Danio 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. Lemon Cichlid (Leleupi) is a known shrimp eater and may prey on small invertebrates or nano fish like Rose Danio.
