Can Sailfin Molly and Skunk Botia Live Together?

Reviewed by Guidarium Editorial DeskUpdated May 11, 2026
Not Recommended

Sailfin Molly and Skunk Botia 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 Sailfin Molly and Skunk Botia?

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

Sailfin Molly is a generally mild-mannered species (3/10), while Skunk Botia is semi-aggressive (7/10). This notable difference means Skunk Botia may occasionally assert dominance over Sailfin Molly.

Sailfin Molly and Skunk Botia 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.

Water Parameters

The safe temperature window for both species falls between 26°C and 28°C. Aim for the midpoint of this range (around 27.0°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: Sailfin Molly needs 15–30 dGH while Skunk Botia requires 2–12 dGH.

Tank Setup

To house Sailfin Molly and Skunk Botia 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: Established Algae (Otocinclus), Plants - Densely covered, Sand (Sifters), Smooth Gravel (Sensitive Barbels), Driftwood (Digestion/Hiding). Meeting these requirements will help both species thrive.

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

Why This Pairing Usually Fails in Practice

Sailfin Molly and Skunk Botia 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 Sailfin Molly and Skunk Botia live together?

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

What size tank do Sailfin Molly and Skunk Botia need?

A minimum of 150 litres (tank length at least 90 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 Sailfin Molly and Skunk Botia together?

Keep the aquarium between 26°C and 28°C. A target of around 27.0°C sits comfortably within both species' preferred ranges.

Are Sailfin Molly or Skunk Botia aggressive?

Sailfin Molly is generally mild-mannered (3/10) and Skunk Botia is semi-aggressive (7/10). The gap in aggression levels means the calmer fish may experience stress from the more assertive one.

What pH do Sailfin Molly and Skunk Botia 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.

Will Skunk Botia nip Sailfin Molly's fins?

Skunk Botia is a known fin nipper. If Sailfin Molly has long or flowing fins, there is a real risk of fin damage. Keeping Skunk Botia in a larger group can help redirect nipping behaviour toward conspecifics.

How do I manage Skunk Botia's territorial behaviour?

Provide line-of-sight breaks using rocks, driftwood, and dense planting. A larger tank gives Skunk Botia space to claim a territory without encroaching on the other fish's area. Adding décor that divides the tank into distinct zones works especially well.
