Can Bamboo Shrimp and Harlequin Rasbora Live Together?

🟡Possible with Caution

Keeping Bamboo Shrimp and Harlequin Rasbora together is possible but requires caution due to potential behavioral clashes. Provide a spacious tank of at least 90 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.

Behaviour & Temperament

Bamboo Shrimp is a peaceful species (0/10), while Harlequin Rasbora is peaceful (1/10). This modest difference means Harlequin Rasbora may occasionally assert dominance over Bamboo Shrimp.

Bamboo Shrimp and Harlequin Rasbora 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: Hyperactive swimmers can stress shy, slow-moving species through constant motion.

Worth noting: Bamboo Shrimp is a known jumper, so a tight-fitting lid is essential.

To improve the chances of a peaceful coexistence in this community tank: A larger aquarium with ample hiding spots can help diffuse aggression and give the less dominant fish space to retreat.

Water Parameters

The safe temperature window for both species falls between 22°C and 28°C. Aim for the midpoint of this range (around 25.0°C) for optimal comfort.

Both fish can tolerate a pH between 6.5 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 6–12 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Bamboo Shrimp and Harlequin Rasbora together, plan for an aquarium of at least 90 litres with a minimum length of 60 cm. This accounts for the larger species' space requirements with an additional 20 % buffer to reduce territorial tension.

Because this pairing requires extra vigilance, include plenty of hiding spots — caves, driftwood, and dense plant clusters — so the less dominant fish can retreat when needed.

Specific environmental needs for this combination include: Driftwood (Digestion/Hiding), Plants - Densely covered, Leaf Litter/Blackwater. Meeting these requirements will help both species thrive.

Both species do well with high (river/stream) water movement, so a standard filtration setup rated for the tank volume should suffice.
