Overview
The moonlight gourami is a calm, slow-moving fish for a quiet community tank. It does best with a keeper who has a little experience.
Did you know
The moonlight gourami is named for its soft, silvery sheen. The sheen comes from unusually fine scales that scatter light across the body.
Caring for the moonlight gourami
Keep moonlight gouramis as a pair or a small group in a quiet tank. A tank of at least 30 gal (115 L) gives a group room to settle. Dense planting with floating plants, calm water and a dark substrate shows off its silvery sheen and helps it feel secure.
It likes warmth, so keep the water at 77 to 86°F (25 to 30°C) with a pH of 6.0 to 7.5. Leave a warm air layer under the lid, as it breathes from the surface and dislikes cold drafts.
Feed a varied diet of flake or pellet, frozen bloodworm, brine shrimp and some vegetable matter. It favors the middle and upper water and explores with its long, thread-like pelvic fins. Avoid known fin-nippers, which will pester those fins. The moonlight gourami mixes well with other peaceful mid-sized community fish, though it can be a little shy at first.
In breeding condition, males develop orange to red pelvic fins and a slightly steeper forehead. They build a large bubble nest, often with plant fragments worked in, and guard the eggs. Home breeding is not commonly recorded.
Good to know
The moonlight gourami belongs to the gourami family Osphronemidae. Its scientific name, microlepis, means small-scaled.
In the wild
Trichopodus microlepis comes from the lowlands of Thailand, Cambodia and Vietnam. It lives in slow and still waters such as swamps, ponds and flooded fields thick with vegetation.
