Can Amano Shrimp and Celestial Pearl Danio (Galaxy Rasbora) Live Together?

Amano Shrimp is a peaceful species (1/10), while Celestial Pearl Danio (Galaxy Rasbora) is peaceful (2/10). This modest difference means Celestial Pearl Danio (Galaxy Rasbora) may occasionally assert dominance over Amano Shrimp.

Amano Shrimp and Celestial Pearl Danio (Galaxy Rasbora) both frequent the Bottom (Substrate) and 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. Aggressive eaters may outcompete shy fish for food, leading to malnutrition.

Worth noting: Amano 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.

The safe temperature window for both species falls between 20°C and 26°C. Aim for the midpoint of this range (around 23.0°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 5–14 dGH. Regular testing will ensure conditions stay within this range.

To house Amano Shrimp and Celestial Pearl Danio (Galaxy Rasbora) together, plan for an aquarium of at least 46 litres with a minimum length of 45 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: Established Algae (Otocinclus), Plants - Densely covered. 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.

Feeding time deserves special attention with this pairing. Amano Shrimp is an aggressive eater that may prevent Celestial Pearl Danio (Galaxy Rasbora) from getting enough food.

Because Amano Shrimp is a fast, competitive feeder, consider using sinking pellets or feeding at opposite ends of the setup to ensure Celestial Pearl Danio (Galaxy Rasbora) receives an adequate share.
