Can your tank handle Bee Shrimp (Crystal Red / Black) and Delicate Blue-Eye?

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 Delicate Blue-Eye is peaceful (1/10). This modest difference means Delicate Blue-Eye may occasionally assert dominance over Bee Shrimp (Crystal Red / Black).

Bee Shrimp (Crystal Red / Black) and Delicate Blue-Eye 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.

Worth noting: Delicate Blue-Eye is a known jumper, so a tight-fitting lid is essential.

Water Parameters

There is no temperature overlap between Bee Shrimp (Crystal Red / Black) (18–24°C) and Delicate Blue-Eye (25–32°C). This fundamental mismatch makes long-term cohabitation impractical.

Both fish can tolerate a pH between 5.5 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.

Tank Setup

To house Bee Shrimp (Crystal Red / Black) and Delicate Blue-Eye together, plan for an aquarium of at least 60 litres with a minimum length of 60 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), Plants - Floating. 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.

Why This Pairing Usually Fails in Practice

Bee Shrimp (Crystal Red / Black) and Delicate Blue-Eye 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.

Frequently Asked Questions

Can Bee Shrimp (Crystal Red / Black) and Delicate Blue-Eye live together?

No. This combination is not recommended. Key incompatibilities — such as non-overlapping temperature ranges — make cohabitation unsafe.

What size tank do Bee Shrimp (Crystal Red / Black) and Delicate Blue-Eye need?

A minimum of 60 litres (tank length at least 60 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 Delicate Blue-Eye together?

Unfortunately, there is no temperature range that satisfies both species. Bee Shrimp (Crystal Red / Black) requires 18–24°C, while Delicate Blue-Eye needs 25–32°C.

Are Bee Shrimp (Crystal Red / Black) or Delicate Blue-Eye aggressive?

Bee Shrimp (Crystal Red / Black) is peaceful (0/10) and Delicate Blue-Eye is peaceful (1/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Bee Shrimp (Crystal Red / Black) and Delicate Blue-Eye need?

Both species overlap in the 5.5–6.8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
