Can Bee Shrimp (Crystal Red / Black) and Scat (Brackish) Live Together?

Reviewed by Guidarium Editorial DeskUpdated April 28, 2026
Not Recommended

Bee Shrimp (Crystal Red / Black) and Scat (Brackish) are not recommended as tank mates due to incompatible water types and conflicting pH requirements and incompatible hardness ranges. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.

Can your tank handle Bee Shrimp (Crystal Red / Black) and Scat (Brackish)?

Compatibility is only part of the answer. Test both fish with your real tank size, current stock, and maintenance needs to see if you have enough space and a safe stocking level before you add them.

Behaviour & Temperament

Bee Shrimp (Crystal Red / Black) is a peaceful species (0/10), while Scat (Brackish) is generally mild-mannered (4/10). This notable difference means Scat (Brackish) may occasionally assert dominance over Bee Shrimp (Crystal Red / Black).

Bee Shrimp (Crystal Red / Black) and Scat (Brackish) 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.

Water Parameters

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 Scat (Brackish) (7.5–8.5) 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 Scat (Brackish) requires 12–30 dGH.

Crucially, these species require different water types — one needs freshwater while the other requires brackish conditions. This is a hard barrier to keeping them together.

Tank Setup

To house Bee Shrimp (Crystal Red / Black) and Scat (Brackish) together, plan for an aquarium of at least 450 litres with a minimum length of 150 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

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), 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 Scat (Brackish) requires Sand (Sifters). These substrate types may be difficult to provide simultaneously. Bee Shrimp (Crystal Red / Black) requires Soil / Nutrient Rich, while Scat (Brackish) requires Smooth Gravel (Sensitive Barbels). These substrate types may be difficult to provide simultaneously. Scat (Brackish) 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.

Bee Shrimp (Crystal Red / Black) prefers Low (Still Water) flow while Scat (Brackish) needs High (River/Stream) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.

Why This Pairing Usually Fails in Practice

Bee Shrimp (Crystal Red / Black) and Scat (Brackish) are the kind of pair that can look acceptable in a shop but become a maintenance problem at home. The main risk is not a single number in the chart; it is the way incompatible behavior, water needs, or pressure on space compounds over time once both fish are established in the same tank.

Suitable Tank Sizes

Standard aquarium sizes large enough for both Bee Shrimp (Crystal Red / Black) and Scat (Brackish).

Diet & Feeding

Feeding time deserves special attention with this pairing. Scat (Brackish) is an aggressive eater that may prevent Bee Shrimp (Crystal Red / Black) from getting enough food.

Because Scat (Brackish) is a fast, competitive feeder, consider using sinking pellets or feeding at opposite ends of the setup to ensure Bee Shrimp (Crystal Red / Black) receives an adequate share.

Frequently Asked Questions

Can Bee Shrimp (Crystal Red / Black) and Scat (Brackish) live together?

No. This combination is not recommended. Key incompatibilities — such as different water type needs — make cohabitation unsafe.

What size tank do Bee Shrimp (Crystal Red / Black) and Scat (Brackish) need?

A minimum of 450 litres (tank length at least 150 cm) is recommended. This provides enough space for both species to establish their own areas and reduces the likelihood of territorial disputes.

What water temperature is best for Bee Shrimp (Crystal Red / Black) and Scat (Brackish) together?

Keep the aquarium between 20°C and 24°C. A target of around 22.0°C sits comfortably within both species' preferred ranges.

Are Bee Shrimp (Crystal Red / Black) or Scat (Brackish) aggressive?

Bee Shrimp (Crystal Red / Black) is peaceful (0/10) and Scat (Brackish) is generally mild-mannered (4/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Bee Shrimp (Crystal Red / Black) and Scat (Brackish) need?

Their pH requirements do not overlap. Bee Shrimp (Crystal Red / Black) prefers 5.5–6.8, while Scat (Brackish) needs 7.5–8.5. This makes them incompatible in the same water chemistry.

Will Scat (Brackish) nip Bee Shrimp (Crystal Red / Black)'s fins?

Scat (Brackish) is a known fin nipper. If Bee Shrimp (Crystal Red / Black) has long or flowing fins, there is a real risk of fin damage. Keeping Scat (Brackish) in a larger group can help redirect nipping behaviour toward conspecifics.
