Behaviour & Temperament

Licorice Gourami is a peaceful species (2/10), while Rosy Red Minnow / Fathead Minnow is peaceful (1/10). This modest difference means Licorice Gourami may occasionally assert dominance over Rosy Red Minnow / Fathead Minnow.

Licorice Gourami and Rosy Red Minnow / Fathead Minnow both frequent the 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.

Additional behavioural considerations to keep in mind: Hyperactive swimmers can stress shy, slow-moving species through constant motion.

Water Parameters

The safe temperature window for both species falls between 22°C and 24°C. Aim for the midpoint of this range (around 23.0°C) for optimal comfort.

The pH requirements of Licorice Gourami (3–6) and Rosy Red Minnow / Fathead Minnow (6.5–8) do not overlap, making it impossible to satisfy both species simultaneously.

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

Tank Setup

To house Licorice Gourami and Rosy Red Minnow / Fathead Minnow together, plan for an aquarium of at least 75 litres with a minimum length of 60 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: Leaf Litter/Blackwater, Plants - Densely covered, Plants - Floating, Driftwood (Digestion/Hiding), Smooth Gravel (Sensitive Barbels). 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

Licorice Gourami and Rosy Red Minnow / Fathead Minnow 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.

What size tank do Licorice Gourami and Rosy Red Minnow / Fathead Minnow need?

A minimum of 75 litres (tank length at least 60 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 Licorice Gourami and Rosy Red Minnow / Fathead Minnow together?

Keep the aquarium between 22°C and 24°C. A target of around 23.0°C sits comfortably within both species' preferred ranges.

Are Licorice Gourami or Rosy Red Minnow / Fathead Minnow aggressive?

Licorice Gourami is peaceful (2/10) and Rosy Red Minnow / Fathead Minnow is peaceful (1/10). Their similar temperaments generally lead to a peaceful coexistence.

What pH do Licorice Gourami and Rosy Red Minnow / Fathead Minnow need?

Their pH requirements do not overlap. Licorice Gourami prefers 3–6, while Rosy Red Minnow / Fathead Minnow needs 6.5–8. This makes them incompatible in the same water chemistry.
