Can Bee Shrimp (Crystal Red / Black) and Red Terror (Festa's Cichlid) Live Together?

Bee Shrimp (Crystal Red / Black) is a peaceful species (0/10), while Red Terror (Festa's Cichlid) is highly aggressive (10/10). This notable difference means Red Terror (Festa's Cichlid) may occasionally assert dominance over Bee Shrimp (Crystal Red / Black).

Large aggression gap (10 points) between Bee Shrimp (Crystal Red / Black) and Red Terror (Festa's Cichlid) increases stress risk for the more peaceful fish.

Bee Shrimp (Crystal Red / Black) and Red Terror (Festa's Cichlid) 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.

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: Aggressive fish may bully and stress shy, slow-moving species.

There is no temperature overlap between Bee Shrimp (Crystal Red / Black) (18–24°C) and Red Terror (Festa's Cichlid) (25–29°C). This fundamental mismatch makes long-term cohabitation impractical.

Both fish can tolerate a pH between 6.5 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 4–6 dGH. Regular testing will ensure conditions stay within this range.

To house Bee Shrimp (Crystal Red / Black) and Red Terror (Festa's Cichlid) 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 Red Terror (Festa's Cichlid) requires Sand (Sifters). These substrate types may be difficult to provide simultaneously. Bee Shrimp (Crystal Red / Black) requires Soil / Nutrient Rich, while Red Terror (Festa's Cichlid) requires Smooth Gravel (Sensitive Barbels). These substrate types may be difficult to provide simultaneously. Red Terror (Festa's Cichlid) 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.

Both species do well with low (still water) water movement, so a standard filtration setup rated for the tank volume should suffice.

Bee Shrimp (Crystal Red / Black) and Red Terror (Festa's Cichlid) 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.
