Blue Gourami (Trichopodus Trichopterus)

Classic, hardy, and beautifully blue — the Blue Gourami (Trichopodus trichopterus, blue form) is a popular and widely kept colour variant of the Three-spot Gourami, displaying a beautiful blue to steel-blue colouration across the body. Hardy, adaptable, and full of personality, the Blue Gourami is a classic community fish that has been a staple of the freshwater hobby for generations.

Overview

Appearance

The Blue Gourami displays a beautiful blue to steel-blue colouration across the body, with two distinctive dark spots — one in the middle of the body and one at the base of the caudal fin — that are characteristic of the Three-spot Gourami (the eye being the third “spot”). The long, thread-like pelvic fins trail gracefully below the body. Males develop a more pointed dorsal fin and display more intense blue colouration during breeding condition.

Water Parameters & Tank Setup

• Temperature: 72 – 82°F (22 – 28°C)
• pH: 6.0 – 8.0
• General Hardness (GH): 5 – 20 dGH

• Plants & Decor: Planted tanks with floating plants and open swimming space; hiding spots appreciated

Diet & Feeding

• Staple: High-quality flake food, pellets, and gourami-specific foods
• Treats: Frozen bloodworms, brine shrimp, daphnia, and blanched vegetables

Feed 2–3 times daily.

Compatibility & Tank Mates

Generally peaceful with most community fish. Good tank mates include tetras, barbs, Corydoras, and livebearers. Males can be territorial with other gouramis — keep one male per tank unless the aquarium is large. Avoid very small fish that may be harassed.

Breeding

Bubble nest builders. Males construct a large floating bubble nest and court females. Eggs are deposited in the nest and guarded by the male. Fry hatch in 24–48 hours.

The Blue Gourami is a hardy and beautiful classic that brings cool blue colour and lively personality to any community aquarium. A timeless favourite for aquarists of all levels.
