Can Altum Angel and Bee Shrimp (Crystal Red / Black) Live Together?

Altum Angel is a moderately assertive species (5/10), while Bee Shrimp (Crystal Red / Black) is peaceful (0/10). This notable difference means Altum Angel may occasionally assert dominance over Bee Shrimp (Crystal Red / Black).

Altum Angel and Bee Shrimp (Crystal Red / Black) 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.

There is a critical concern: the Piscivore (Eats small/nano fish) behaviour of one fish directly conflicts with the Nano / Bite-sized (Predation Risk) 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.

There is no temperature overlap between Altum Angel (27–32°C) and Bee Shrimp (Crystal Red / Black) (18–24°C). This fundamental mismatch makes long-term cohabitation impractical.

Both fish can tolerate a pH between 5.5 and 6.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 3–5 dGH. Regular testing will ensure conditions stay within this range.

To house Altum Angel and Bee Shrimp (Crystal Red / Black) together, plan for an aquarium of at least 400 litres with a minimum length of 120 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: Sand (Sifters), Driftwood (Digestion/Hiding), Leaf Litter/Blackwater, Plants - Floating, Soil / Nutrient Rich, Plants - Densely covered, Established Algae (Otocinclus). Meeting these requirements will help both species thrive.

Note a potential conflict in setup requirements: Altum Angel requires Sand (Sifters), while Bee Shrimp (Crystal Red / Black) requires Soil / Nutrient Rich. 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.

Altum Angel and Bee Shrimp (Crystal Red / Black) 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.

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