Can Blind Cave Tetra and Red Goldflake Shrimp Live Together?

Blind Cave Tetra is a generally mild-mannered species (4/10), while Red Goldflake Shrimp is peaceful (0/10). This notable difference means Blind Cave Tetra may occasionally assert dominance over Red Goldflake Shrimp.

Blind Cave Tetra 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. Aggressive eaters may outcompete shy fish for food, leading to malnutrition.

There is no temperature overlap between Blind Cave Tetra (20–25°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. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 8–10 dGH. Regular testing will ensure conditions stay within this range.

To house Blind Cave Tetra and Red Goldflake Shrimp 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: Smooth Gravel (Sensitive Barbels), Sand (Sifters), 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.

Blind Cave Tetra 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. Blind Cave Tetra is an aggressive eater that may prevent Red Goldflake Shrimp from getting enough food.

Because Blind Cave Tetra is a fast, competitive feeder, consider using sinking pellets or feeding at opposite ends of the setup to ensure Red Goldflake Shrimp receives an adequate share.
