Can Red Tupfel Shrimp and Sailfin Molly Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 11, 2026
Not Recommended

Red Tupfel Shrimp and Sailfin Molly are not recommended as tank mates due to incompatible hardness ranges. Housing these species together is likely to result in stress, health problems, or direct harm to one or both fish.

Can your tank handle Red Tupfel Shrimp and Sailfin Molly?

Compatibility is only part of the answer. Test both fish with your real tank size, current stock, and maintenance needs to see if you have enough space and a safe stocking level before you add them.

Behaviour & Temperament

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

Red Tupfel Shrimp and Sailfin Molly 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.

Water Parameters

The safe temperature window for both species falls between 22°C and 25°C. Aim for the midpoint of this range (around 23.5°C) for optimal comfort.

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

Hardness requirements are incompatible: Red Tupfel Shrimp needs 4–10 dGH while Sailfin Molly requires 15–30 dGH.

Tank Setup

To house Red Tupfel Shrimp and Sailfin Molly together, plan for an aquarium of at least 110 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: Established Algae (Otocinclus), Plants - Densely covered, Leaf Litter/Blackwater. Meeting these requirements will help both species thrive.

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

Why This Pairing Usually Fails in Practice

Red Tupfel Shrimp and Sailfin Molly 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.

Frequently Asked Questions

Can Red Tupfel Shrimp and Sailfin Molly live together?

No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.

What size tank do Red Tupfel Shrimp and Sailfin Molly need?

A minimum of 110 litres (tank length at least 80 cm) is recommended. This provides enough space for both species to establish their own areas and reduces the likelihood of territorial disputes.

What water temperature is best for Red Tupfel Shrimp and Sailfin Molly together?

Keep the aquarium between 22°C and 25°C. A target of around 23.5°C sits comfortably within both species' preferred ranges.

Are Red Tupfel Shrimp or Sailfin Molly aggressive?

Red Tupfel Shrimp is peaceful (0/10) and Sailfin Molly is generally mild-mannered (3/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Red Tupfel Shrimp and Sailfin Molly need?

Both species overlap in the 7.5–7.5 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
