Can Garnet Tetra and Ocellatus Gold Live Together?

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

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

In terms of spatial distribution, Garnet Tetra prefers the Middle (Open Water) zone, whereas Ocellatus Gold occupies the Bottom (Substrate) 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: Aggressive fish may bully and stress shy, slow-moving species. 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 Garnet Tetra (5–7) and Ocellatus Gold (8–9) do not overlap, making it impossible to satisfy both species simultaneously.

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

To house Garnet Tetra and Ocellatus Gold 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: Plants - Densely covered, Plants - Floating, Leaf Litter/Blackwater, Sand (Sifters), Shells (Breeding/Hiding). Meeting these requirements will help both species thrive.

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

Garnet Tetra and Ocellatus Gold 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 Garnet Tetra.
