Can Bee Shrimp (Crystal Red / Black) and Green Phantom Pleco (L200) Live Together?

Bee Shrimp (Crystal Red / Black) is a peaceful species (0/10), while Green Phantom Pleco (L200) is moderately assertive (5/10). This notable difference means Green Phantom Pleco (L200) may occasionally assert dominance over Bee Shrimp (Crystal Red / Black).

Bee Shrimp (Crystal Red / Black) and Green Phantom Pleco (L200) 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.

Worth noting: Green Phantom Pleco (L200) 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 Green Phantom Pleco (L200) (25–30°C). This fundamental mismatch makes long-term cohabitation impractical.

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

To house Bee Shrimp (Crystal Red / Black) and Green Phantom Pleco (L200) together, plan for an aquarium of at least 250 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: 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 Green Phantom Pleco (L200) requires Smooth Gravel (Sensitive Barbels). These substrate types may be difficult to provide simultaneously. Green Phantom Pleco (L200) 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.

Bee Shrimp (Crystal Red / Black) prefers Low (Still Water) flow while Green Phantom Pleco (L200) 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 Green Phantom Pleco (L200) 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.
