Can Delicate Blue-Eye and Licorice Gourami Live Together?
Delicate Blue-Eye and Licorice Gourami 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.
At a Glance
Can your tank handle Delicate Blue-Eye and Licorice Gourami?
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
Delicate Blue-Eye is a peaceful species (1/10), while Licorice Gourami is peaceful (2/10). This modest difference means Licorice Gourami may occasionally assert dominance over Delicate Blue-Eye.
Delicate Blue-Eye and Licorice Gourami 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.
Worth noting: Delicate Blue-Eye is a known jumper, so a tight-fitting lid is essential.
Water Parameters
The safe temperature window for both species falls between 25°C and 28°C. Aim for the midpoint of this range (around 26.5°C) for optimal comfort.
Both fish can tolerate a pH between 5 and 6. Maintaining a stable value within this band is more important than hitting an exact number.
Hardness requirements are incompatible: Delicate Blue-Eye needs 5–15 dGH while Licorice Gourami requires 0–4 dGH.
Tank Setup
To house Delicate Blue-Eye and Licorice Gourami together, plan for an aquarium of at least 60 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: Plants - Densely covered, Plants - Floating, Leaf Litter/Blackwater, 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
Delicate Blue-Eye and Licorice Gourami 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 Delicate Blue-Eye and Licorice Gourami live together?
No. This combination is not recommended. Key incompatibilities — such as critical behavioural conflicts — make cohabitation unsafe.
What size tank do Delicate Blue-Eye and Licorice Gourami need?
A minimum of 60 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 Delicate Blue-Eye and Licorice Gourami together?
Keep the aquarium between 25°C and 28°C. A target of around 26.5°C sits comfortably within both species' preferred ranges.
Are Delicate Blue-Eye or Licorice Gourami aggressive?
Delicate Blue-Eye is peaceful (1/10) and Licorice Gourami is peaceful (2/10). Their similar temperaments generally lead to a peaceful coexistence.
What pH do Delicate Blue-Eye and Licorice Gourami need?
Both species overlap in the 5–6 pH range. Consistency is key — avoid sudden swings, and test regularly to stay within this window.
