Can Bee Shrimp (Crystal Red / Black) and Giant Gourami Live Together?

Bee Shrimp (Crystal Red / Black) is a peaceful species (0/10), while Giant Gourami is moderately assertive (6/10). This notable difference means Giant Gourami may occasionally assert dominance over Bee Shrimp (Crystal Red / Black).

Large aggression gap (6 points) between Bee Shrimp (Crystal Red / Black) and Giant Gourami increases stress risk for the more peaceful fish.

Bee Shrimp (Crystal Red / Black) and Giant Gourami 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.

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 (Crystal Red / Black) and Giant Gourami 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 6.5 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 (Crystal Red / Black) and Giant Gourami together, plan for an aquarium of at least 1200 litres with a minimum length of 200 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: Soil / Nutrient Rich, Plants - Densely covered, Driftwood (Digestion/Hiding), Leaf Litter/Blackwater, Established Algae (Otocinclus), Smooth Gravel (Sensitive Barbels). Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Bee Shrimp (Crystal Red / Black) requires Soil / Nutrient Rich, while Giant Gourami requires Smooth Gravel (Sensitive Barbels). These substrate types may be difficult to provide simultaneously. Giant Gourami is a plant destroyer, which conflicts with Bee Shrimp (Crystal Red / Black)'s requirement for live plants. Compromise where possible or prioritise the more critical need.

Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.
