Dwarf Gourami Female

Dwarf Gourami Female (Trichogaster lalius, formerly Colisa lalia)

Appearance & Behavior

Female Dwarf Gouramis bring a soft, silvery shimmer and gentle movement to a planted freshwater aquarium. Their coloration is typically more subdued than the bold red and blue of males, with delicate markings and slender, feeler-like pelvic fins used to explore their surroundings. Watch her weave through leafy cover before rising to the surface for a breath of air. Generally shy and peaceful, females do best in calm surroundings where they can feed without competition.

Quick Care Guide

• Care level: moderate; stable water quality and a low-stress environment are important.
• Temperament: generally peaceful, though individual gouramis may chase one another.
• Adult size: approximately 2–3 inches.
• Aquarium: 20 gallons or larger is recommended for a comfortable community setup; provide more space for multiple gouramis.
• Temperature: 75–82°F.
• pH: approximately 6.0–7.5; prioritize stability over chasing a particular number.
• Water hardness: soft to moderately hard freshwater.
• Diet: omnivore; small prepared foods with appropriately sized frozen or live foods for variety.
• Swimming area: primarily middle and upper levels, with clear access to the surface.

Aquarium Setup & Compatibility

Provide a fully cycled aquarium with live plants, gentle filtration, and shaded retreats. Floating plants can help her feel secure, but leave open areas for surface breathing and feeding. A secure lid with an air space above the water is important. Maintain clean water through regular water changes and avoid sudden changes in temperature or water chemistry.

Suitable companions include peaceful rasboras, small tetras, and Corydoras. Avoid aggressive fish, fin nippers, and boisterous feeders that may intimidate her or monopolize food. Small shrimp and shrimplets may be eaten.

A female does not need a male companion to thrive. Keeping a male and female together is not a guarantee of compatibility, as males can persistently chase females, particularly during breeding. If keeping more than one gourami, provide additional space, dense planting, and visual barriers, and be prepared to separate fish if harassment continues. Quarantine new arrivals and monitor appetite, activity, and body condition before introducing them to an established community.

Feeding

Offer quality tropical flakes or small floating and slow-sinking pellets sized for her mouth. Supplement with foods such as daphnia, brine shrimp, and occasional bloodworms. Feed modest portions once or twice daily, ensuring she gets food even when kept with quicker tankmates. Remove uneaten food to help maintain water quality.
