Blue Gourami (Trichopodus trichopterus) 3-5cm
The blue gourami (Trichopodus trichopterus), also called the three-spot gourami, is a popular, hardy, and vibrant freshwater fish native to Southeast Asia. It is highly favored by both beginners and expert hobbyists due to its striking color and adaptability.
Quick Species Overview
Scientific Name: Trichopodus trichopterus
Adult Size: Up to 15 cm (6 inches)
Lifespan: 4 to 6 yearsCare Level: Easy and excellent for beginners
Key Feature: Possesses a labyrinth organ that allows them to breathe atmospheric air directly from the surface.
The "Three Spots": They feature two distinct black spots on their body (one mid-body and one at the tail base), with the eye counting as the third spot.
Tank Setup & Water Parameters
Blue gouramis naturally inhabit slow-moving or stagnant waters, such as swamps, marshes, and flooded plains.
Minimum Tank Size: 30 gallons for a single fish or a pair. A community tank requires 40 gallons or more.
Temperature: Keep water between 22°C to 28°C (72°F to 82°F).
pH Range: Very flexible, ranging from 6.0 to 8.0.
Water Movement: Use gentle filtration. They dislike strong water currents.
Plants & Decor: Heavy planting is ideal. Use floating plants and driftwood to create hiding spots and mimic their natural habitat. Keep a clear gap of air at the top of the tank so they can breathe.
Diet & Feeding Habits
These fish are omnivores with a leaning toward small prey. They are not picky eaters.
Daily Base: High-quality tropical flakes or sinking pellets.
Protein Boosts: Offer frozen or live food like bloodworms, brine shrimp, and daphnia 2–3 times a week.
Pest Control: They are famous for eating aquarium pests like snails and hydra.
Compatibility & Temperament
While generally peaceful when young, blue gouramis can become territorial and aggressive as they mature or during breeding.
Ideal Tankmates: Keep them with fast, mid-sized fish like barbs, tetras, rasboras, corydoras catfish, and loaches.
Fish to Avoid: Do not house them with other male gouramis or male Bettas to prevent fighting. Avoid fish with long, flowing fins (like fancy guppies or angelfish), as gouramis may nip at them.
Stocking Ratio: Keep only one male per tank, paired with one or two females to distribute any aggressive chasing.
