Can Bee Shrimp (Crystal Red / Black) and Fire Eel Live Together?

🔴Not Recommended

Bee Shrimp (Crystal Red / Black) and Fire Eel are not recommended as tank mates due to piscivorous fish will prey on nano-sized tank mates.. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.

Behaviour & Temperament

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

Bee Shrimp (Crystal Red / Black) and Fire Eel 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.

There is a critical concern: the Nano / Bite-sized (Predation Risk) behaviour of one fish directly conflicts with the Piscivore (Eats small/nano fish) trait of the other — piscivorous fish will prey on nano-sized tank mates..

Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion. Shrimp eaters may also prey on very small nano fish.

Worth noting: Fire Eel is nocturnal and will be most active after lights-out, naturally reducing daytime encounters. Also, Fire Eel is a known jumper, so a tight-fitting lid is essential.

Water Parameters

The safe temperature window for both species falls between 24°C and 24°C. Aim for the midpoint of this range (around 24.0°C) for optimal comfort.

Both fish can tolerate a pH between 6 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 Fire Eel together, plan for an aquarium of at least 816 litres with a minimum length of 180 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), 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 Fire Eel requires Sand (Sifters). These substrate types may be difficult to provide simultaneously. Bee Shrimp (Crystal Red / Black) requires Soil / Nutrient Rich, while Fire Eel requires Smooth Gravel (Sensitive Barbels). 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.

Diet & Feeding

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

Frequently Asked Questions

Can Bee Shrimp (Crystal Red / Black) and Fire Eel live together?

No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.

What size tank do Bee Shrimp (Crystal Red / Black) and Fire Eel need?

A minimum of 816 litres (tank length at least 180 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 Fire Eel together?

Keep the aquarium between 24°C and 24°C. A target of around 24.0°C sits comfortably within both species' preferred ranges.

Are Bee Shrimp (Crystal Red / Black) or Fire Eel aggressive?

Bee Shrimp (Crystal Red / Black) is peaceful (0/10) and Fire Eel 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 Fire Eel need?

Both species overlap in the 6–6.8 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.

Does Fire Eel being nocturnal affect compatibility?

Fire Eel is most active after lights-out, which naturally reduces daytime encounters with its tank mate. This can actually be beneficial, as both fish get undisturbed time to feed and explore. Just ensure food reaches Fire Eel during evening hours.
