Can Bee Shrimp and Siamese Algae Eater Live Together?

Bee Shrimp is a peaceful species (0/10), while Siamese Algae Eater is generally mild-mannered (3/10). This modest difference means Siamese Algae Eater may occasionally assert dominance over Bee Shrimp.

Bee Shrimp and Siamese Algae Eater 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.

Worth noting: Siamese Algae Eater is a known jumper, so a tight-fitting lid is essential.

To improve the chances of a peaceful coexistence in this community tank: Provide a significantly larger tank (at least 50% more volume than the minimum) to allow both Bee Shrimp and Siamese Algae Eater to establish separate territories. Add plenty of line-of-sight breaks using driftwood, rocks, and dense planting to reduce territorial confrontations. 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 22°C and 24°C. Aim for the midpoint of this range (around 23.0°C) for optimal comfort.

Both fish can tolerate a pH between 6 and 6.8. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 5–6 dGH. Regular testing will ensure conditions stay within this range.

To house Bee Shrimp and Siamese Algae Eater together, plan for an aquarium of at least 110 litres with a minimum length of 90 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

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: Soil / Nutrient Rich, Leaf Litter/Blackwater, Plants - Densely covered, Established Algae (Otocinclus), Driftwood (Digestion/Hiding), Plants - lighly covered. 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.

Feeding time deserves special attention with this pairing. Siamese Algae Eater is an aggressive eater that may prevent Bee Shrimp from getting enough food.

Because Siamese Algae Eater is a fast, competitive feeder, consider using sinking pellets or feeding at opposite ends of the setup to ensure Bee Shrimp receives an adequate share.
