Variety of Blue Gourami · cosby
📍 Southeast Asia
The Cosby Gourami is a selectively bred form with a marbled blue, gray, and white pattern. Like other three-spot gouramis, males are territorial toward one another and do best kept one per tank.
Care Guide
Diet
Cosby Gouramis are omnivores that thrive on a varied diet of high-quality flake foods, small pellets, and regular offerings of frozen foods such as brine shrimp, daphnia, and bloodworms. Feed small amounts once daily, only what they can consume in 2-3 minutes. Supplement occasionally with blanched vegetables like zucchini to support digestive health.
Behavior
Cosby Gouramis are labyrinth breathers that spend time at the water surface and are generally peaceful but territorial, especially males toward each other. They are moderately active, often exploring plants and décor, and display curious, interactive behavior with their environment. Males will construct bubble nests and become aggressive during breeding season.
Breeding
Breeding in captivity is moderately difficult and requires specific conditions including warm water (26-28°C), dense floating plants for nest building, and isolation of the breeding pair. Males build elaborate bubble nests and guard eggs and fry aggressively; females should be removed after spawning to prevent harassment. Fry are tiny and require infusoria or liquid fry food for the first week before accepting microworms.
Tank Mates
Peaceful bottom-dweller that won't compete with gouramis and helps control algae
Small, schooling fish that occupy mid-water and avoid territorial conflicts
Large enough to avoid predation and help with algae control without competing for food
Algae-eating snail that won't be harmed by gouramis and maintains tank cleanliness
Common Diseases
Ich (White Spot Disease)
White spots on body and fins, rapid breathing, lethargy, rubbing against objects
Raise temperature gradually to 28-30°C, perform daily 25% water changes, use aquarium salt (1 teaspoon per 5 gallons) or commercial ich treatment for 7-10 days
Fin Rot
Frayed or deteriorating fins, discoloration at fin edges, lethargy
Improve water quality with frequent partial water changes, remove any sharp décor, treat with antibacterial medication if severe, ensure good filtration
Labyrinth Organ Infection
Difficulty breathing at surface, gasping, swollen gill area, loss of appetite
Maintain excellent water quality and stable temperature, ensure access to water surface for air breathing, use broad-spectrum antibiotics if bacterial infection is suspected
Velvet Disease
Fine gold or rust-colored dust on body, rapid breathing, scratching behavior, lethargy
Raise temperature to 28-30°C, perform daily water changes, treat with copper-free medication, reduce light exposure during treatment
