Can Bee Shrimp (Crystal Red / Black) and Knight Goby Live Together?

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

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

Bee Shrimp (Crystal Red / Black) and Knight Goby 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: Shrimp eaters may also prey on very small nano fish.

The safe temperature window for both species falls between 20°C and 24°C. Aim for the midpoint of this range (around 22.0°C) for optimal comfort.

The pH requirements of Bee Shrimp (Crystal Red / Black) (5.5–6.8) and Knight Goby (7–8.5) do not overlap, making it impossible to satisfy both species simultaneously.

Hardness requirements are incompatible: Bee Shrimp (Crystal Red / Black) needs 3–6 dGH while Knight Goby requires 10–30 dGH.

To house Bee Shrimp (Crystal Red / Black) and Knight Goby 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.

Providing a mix of open swimming space and sheltered areas with rocks, driftwood, or plants will keep both species comfortable and allow natural behaviour.

Specific environmental needs for this combination include: Soil / Nutrient Rich, Plants - Densely covered, Driftwood (Digestion/Hiding), Leaf Litter/Blackwater, Established Algae (Otocinclus), Sand (Sifters), Shells (Breeding/Hiding). 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 Knight Goby requires Sand (Sifters). These substrate types may be difficult to provide simultaneously. 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.

Feeding time deserves special attention with this pairing. Knight Goby is a known shrimp eater and may prey on small invertebrates or nano fish like Bee Shrimp (Crystal Red / Black).
