Moonlight Gourami Tank Setup
Give them at least 115 litres (30 US gallons) with gentle flow, water at 77-86°F, and a pH around 6-7.8. Gouramis breathe air at the surface, so keep it clear of thick film. They reach about 15 cm as adults, so don't be misled by the small juveniles sold in stores.
What Do Moonlight Gouramis Eat?
They're not fussy eaters - feed a varied diet, rotating good-quality dry, frozen, and gel foods rather than the same thing every day, and match the food size to their mouths.
Moonlight Gourami Tank Mates
The Moonlight Gourami is semi-aggressive, which is the first thing to weigh up when you choose tank mates. Good matches come down to the whole stocking list working together - temperature, tank size, and temperament - not any single label. Before you buy, run your full stocking list through our stocking calculator. It weighs temperament, adult size, and water needs together, which a single species page can't do on its own.
Are Moonlight Gouramis Good for Beginners?
Doable once you test water regularly and catch problems before fish look sick. If this is your first tank, pick something more forgiving and come back later.
Moonlight Gourami - frequently asked questions
What size tank do Moonlight Gouramis need?
Moonlight Gouramis need a tank of at least 115 litres (30 US gallons). A bigger tank is always easier to keep stable, and gives them more room to settle in and behave naturally.
What water parameters do Moonlight Gouramis need?
Keep them at 77-86°F with a pH of 6-7.8, steady rather than chased to an exact figure. In a cycled tank, ammonia and nitrite should both read 0 ppm, with nitrate kept low through regular water changes.
What do Moonlight Gouramis eat?
Moonlight Gouramis are omnivores and aren't fussy eaters. Feed a varied mix of good-quality dry, frozen, and gel foods, and match the food size to their mouths. Feed small amounts once or twice a day, and remove anything they don't eat.
Are Moonlight Gouramis good for beginners?
Moonlight Gouramis are best for keepers with a little experience. They are manageable once you test water regularly and catch problems early; a complete beginner may prefer something more forgiving first.
Common mistakes with Moonlight Gouramis
- Underestimating tank size - the minimum footprint is 115 litres (30 US gallons); impulse buying into a smaller tank leads to stress and shortened lifespan.
