Can Bee Shrimp (Crystal Red / Black) and Contradens Pleco (Snowball Variant) Live Together?

Bee Shrimp (Crystal Red / Black) is a peaceful species (0/10), while Contradens Pleco (Snowball Variant) is generally mild-mannered (3/10). This modest difference means Contradens Pleco (Snowball Variant) may occasionally assert dominance over Bee Shrimp (Crystal Red / Black).

Bee Shrimp (Crystal Red / Black) and Contradens Pleco (Snowball Variant) 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.

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: Contradens Pleco (Snowball Variant) is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.

There is no temperature overlap between Bee Shrimp (Crystal Red / Black) (18–24°C) and Contradens Pleco (Snowball Variant) (25–29°C). This fundamental mismatch makes long-term cohabitation impractical.

Both fish can tolerate a pH between 5.8 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 Contradens Pleco (Snowball Variant) together, plan for an aquarium of at least 120 litres with a minimum length of 80 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), 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 Contradens Pleco (Snowball Variant) requires Smooth Gravel (Sensitive Barbels). These substrate types may be difficult to provide simultaneously. Compromise where possible or prioritise the more critical need.

Bee Shrimp (Crystal Red / Black) prefers Low (Still Water) flow while Contradens Pleco (Snowball Variant) needs High (River/Stream) flow. Consider positioning filter outlets and using baffles to create zones of different current intensity within the same tank.

Bee Shrimp (Crystal Red / Black) and Contradens Pleco (Snowball Variant) 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. Contradens Pleco (Snowball Variant) is a known shrimp eater and may prey on small invertebrates or nano fish like Bee Shrimp (Crystal Red / Black).
