Croaking Gourami

The Croaking Gourami is a small labyrinth fish known for the distinctive croaking sounds males make using their pectoral fins. Slightly larger than the Sparkling Gourami, they have a more elongated body with horizontal stripes and iridescent coloring. Native to Southeast Asia, they are labyrinth fish that breathe air from the surface. While generally peaceful, males can be territorial toward each other and other gourami species. They are best kept in pairs or with one male and multiple females.

Care Requirements

Tank Setup

Croaking Gouramis need planted tanks with surface access.

Essential Setup:

• 20+ gallons
• Moderate to dense planting
• Floating plants
• Gentle filtration
• Surface access for breathing
• Driftwood and caves

Water Quality

• Temperature: 72-82°F (22-28°C)
• pH: 6.0-7.5
• Water Hardness: Soft to moderate (3-12 dGH)
• Ammonia/Nitrite: 0 ppm
• Nitrate: <20 ppm

Feeding

Omnivores accepting most foods:

• Quality flakes or small pellets
• Frozen bloodworms, brine shrimp
• Live foods enhance color
• Will eat small insects

The Croaking

Distinctive sound production:

• Males croak: During displays and courtship
• Pectoral fins: Rub together to create sound
• Loudest: Early morning and evening
• Purpose: Territorial and mating displays

Behavior & Compatibility

Semi-aggressive toward their own kind:

• Territorial: Males defend space
• Peaceful to other species: Good community fish
• Labyrinth fish: Need surface access
• Shy: Like plant cover

Good Tank Mates:

• Peaceful tetras
• Corydoras
• Rasboras
• Small peaceful fish

Avoid:

• Other gourami species
• Betta fish
• Fin nippers

Sexing

• Males: More colorful, longer fins, croak
• Females: Duller, shorter fins, rounder

Breeding

Bubble nest builder:

• Male builds nest: At surface among plants
• Condition: Feed well, separate pair
• Spawning: Under floating plants
• Fry care: Male guards initially
• Tiny fry: Feed infusoria

Tips for Success

• Keep one male per tank (usually)
• Provide dense planting
• Ensure surface access
• Feed varied diet
• Listen for croaking at dawn and dusk
