Can Ocellatus Gold and Rosy Finned Tetra Live Together?

Ocellatus Gold is a semi-aggressive species (8/10), while Rosy Finned Tetra is peaceful (1/10). This notable difference means Ocellatus Gold may occasionally assert dominance over Rosy Finned Tetra.

Large aggression gap (7 points) between Ocellatus Gold and Rosy Finned Tetra increases stress risk for the more peaceful fish.

In terms of spatial distribution, Ocellatus Gold prefers the Bottom (Substrate) zone, whereas Rosy Finned Tetra occupies the Middle (Open Water) zone. Because they use different levels of the water column, territorial disputes are less likely and the tank will appear more balanced.

Additional behavioural considerations to keep in mind: Shrimp eaters may also prey on very small nano fish.

The safe temperature window for both species falls between 24°C and 27°C. Aim for the midpoint of this range (around 25.5°C) for optimal comfort.

The pH requirements of Ocellatus Gold (8–9) and Rosy Finned Tetra (5.5–7.5) do not overlap, making it impossible to satisfy both species simultaneously.

For general hardness, the shared comfort zone is 10–12 dGH. Regular testing will ensure conditions stay within this range.

To house Ocellatus Gold and Rosy Finned Tetra together, plan for an aquarium of at least 60 litres with a minimum length of 60 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), Shells (Breeding/Hiding), Plants - Densely covered, Leaf Litter/Blackwater. 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.

Ocellatus Gold and Rosy Finned Tetra 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. Ocellatus Gold is a known shrimp eater and may prey on small invertebrates or nano fish like Rosy Finned Tetra.
