Can Orangespotted Sunfish and Red Goldflake Shrimp Live Together?

Orangespotted Sunfish is a moderately assertive species (6/10), while Red Goldflake Shrimp is peaceful (0/10). This notable difference means Orangespotted Sunfish may occasionally assert dominance over Red Goldflake Shrimp.

Large aggression gap (6 points) between Orangespotted Sunfish and Red Goldflake Shrimp increases stress risk for the more peaceful fish.

Orangespotted Sunfish and Red Goldflake Shrimp both frequent the Bottom (Substrate) 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: Hyperactive swimmers can stress shy, slow-moving species through constant motion. Shrimp eaters may also prey on very small nano fish.

There is no temperature overlap between Orangespotted Sunfish (10–25°C) and Red Goldflake Shrimp (26–29°C). This fundamental mismatch makes long-term cohabitation impractical.

Both fish can tolerate a pH between 7.5 and 8.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 5–10 dGH. Regular testing will ensure conditions stay within this range.

To house Orangespotted Sunfish and Red Goldflake Shrimp together, plan for an aquarium of at least 75 litres with a minimum length of 75 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), Driftwood (Digestion/Hiding), Established Algae (Otocinclus). 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.

Orangespotted Sunfish and Red Goldflake Shrimp 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. Orangespotted Sunfish is a known shrimp eater and may prey on small invertebrates or nano fish like Red Goldflake Shrimp.
