Can Peppermint Pleco and Red Tupfel Shrimp Live Together?

Peppermint Pleco is a generally mild-mannered species (3/10), while Red Tupfel Shrimp is peaceful (0/10). This modest difference means Peppermint Pleco may occasionally assert dominance over Red Tupfel Shrimp.

Peppermint Pleco and Red Tupfel Shrimp 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: Peppermint Pleco is nocturnal and will be most active after lights-out, naturally reducing daytime encounters.

There is no temperature overlap between Peppermint Pleco (26–30°C) and Red Tupfel Shrimp (18–25°C). This fundamental mismatch makes long-term cohabitation impractical.

Both fish can tolerate a pH between 6.5 and 7.5. Maintaining a stable value within this band is more important than hitting an exact number.

For general hardness, the shared comfort zone is 4–10 dGH. Regular testing will ensure conditions stay within this range.

To house Peppermint Pleco and Red Tupfel Shrimp together, plan for an aquarium of at least 150 litres with a minimum length of 90 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: Driftwood (Digestion/Hiding), Smooth Gravel (Sensitive Barbels), Established Algae (Otocinclus), Plants - Densely covered, Leaf Litter/Blackwater. Meeting these requirements will help both species thrive.

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

Peppermint Pleco and Red Tupfel Shrimp 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.
