Can Bee Shrimp (Crystal Red / Black) and Blue Tetra Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 2, 2026
Possible with Caution

Keeping Bee Shrimp (Crystal Red / Black) and Blue Tetra together is possible but requires caution due to differing aggression levels and potential behavioral clashes. Provide a spacious tank of at least 90 litres with plenty of hiding spots to reduce stress. Monitor behaviour closely, especially during the first few weeks.

Can your tank handle Bee Shrimp (Crystal Red / Black) and Blue Tetra?

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 Blue Tetra is moderately assertive (5/10). This notable difference means Blue Tetra may occasionally assert dominance over Bee Shrimp (Crystal Red / Black).

Bee Shrimp (Crystal Red / Black) and Blue Tetra 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: Blue Tetra 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. Keep fin nippers in larger groups to distribute nipping behaviour among conspecifics rather than tank mates.

Water Parameters

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 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 3–6 dGH. Regular testing will ensure conditions stay within this range.

Tank Setup

To house Bee Shrimp (Crystal Red / Black) and Blue Tetra together, plan for an aquarium of at least 90 litres with a minimum length of 90 cm. This recommendation combines the stricter species minimums with a community-load allowance so the pairing has realistic long-term space and filtration headroom.

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). 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 Needs Extra Planning in Practice

This pairing usually fails when the tank is treated like a standard mixed community and the caution flags are ignored. Bee Shrimp (Crystal Red / Black) and Blue Tetra need extra room, more cover, and closer observation during the first few weeks so small aggression, feeding, or territory issues do not snowball into a long-term problem.

Frequently Asked Questions

Can Bee Shrimp (Crystal Red / Black) and Blue Tetra live together?

They can coexist, but the pairing requires careful monitoring. Provide ample space (at least 90 litres), plenty of hiding spots, and watch for signs of stress or aggression.

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

A minimum of 90 litres (tank length at least 90 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 Blue Tetra together?

Keep the aquarium between 22°C and 24°C. A target of around 23.0°C sits comfortably within both species' preferred ranges.

Are Bee Shrimp (Crystal Red / Black) or Blue Tetra aggressive?

Bee Shrimp (Crystal Red / Black) is peaceful (0/10) and Blue Tetra is moderately assertive (5/10). 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 Blue Tetra 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.

Will Blue Tetra nip Bee Shrimp (Crystal Red / Black)'s fins?

Blue Tetra 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 Blue Tetra in a larger group can help redirect nipping behaviour toward conspecifics.
