Giant gouramis (Osphronemus goramy) are large, intelligent freshwater fish native to Southeast Asia. They’re hardy and relatively easy to care for if their needs are met, but due to their size and temperament, they’re best suited for experienced aquarists or those prepared for a long-term commitment.
 
Here’s a care guide to get you started:
 
 
 
 
Tank Setup
 
 
Tank Size: Minimum 200 gallons (750+ litres) for adults; they can grow up to 24 inches (60 cm).
Tankmates: Best kept alone or with similarly sized, peaceful fish. Avoid small fish (they might eat them) and aggressive species.
Substrate & Decor: Sand or fine gravel. Provide hiding places with driftwood and large rocks, but leave plenty of open swimming space.
Plants: Can be destructive to live plants, but tough species like Java fern or Anubias might survive.
 
 
 
 
 
Water Parameters
 
 
Temperature: 25–30°C (77–86°F)
pH: 6.5–8.0
Hardness: Moderate
Filtration: Strong filtration is essential due to their size and waste production. A canister filter is recommended.
Water Changes: 25–50% weekly to maintain water quality.
 
 
 
 
 
Diet
 
 
Omnivores: They eat a variety of foods.
Foods to offer: Pellets, vegetables (like spinach, peas, and lettuce), live/frozen food (earthworms, shrimp, insects), and occasional fruit.
Avoid: Overfeeding or only offering one type of food — variety is key.
 
 
 
 
 
Behaviour & Temperament
 
 
Can become territorial, especially with age.
Intelligent and often recognize their owners.
May become aggressive in confined spaces or with unsuitable tankmates.
 
 
 
 
 
Health Tips
 
 
Watch for signs of poor water quality (clamped fins, loss of appetite).
Avoid sudden changes in temperature or pH.
Quarantine new fish if adding tankmates.
 
 
 
 
 
Fun Fact
 
 
They can breathe air thanks to a labyrinth organ, so you’ll sometimes see them gulping at the surface.
