Can Bee Shrimp (Crystal Red / Black) and Dojo Loach (Weather Loach) Live Together?

Bee Shrimp (Crystal Red / Black) is a peaceful species (0/10), while Dojo Loach (Weather Loach) is peaceful (2/10). This modest difference means Dojo Loach (Weather Loach) may occasionally assert dominance over Bee Shrimp (Crystal Red / Black).

Bee Shrimp (Crystal Red / Black) and Dojo Loach (Weather Loach) 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.

Worth noting: Dojo Loach (Weather Loach) 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 18°C and 24°C. Aim for the midpoint of this range (around 21.0°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 Dojo Loach (Weather Loach) together, plan for an aquarium of at least 240 litres with a minimum length of 120 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), Sand (Sifters). 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 Dojo Loach (Weather Loach) requires Sand (Sifters). These substrate types may be difficult to provide simultaneously. Dojo Loach (Weather Loach) 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.
