Brochis splendens (Green Cory)

Brochis splendens, widely known as the Emerald Catfish, is a peaceful, hardy South American armored catfish. Growing to a maximum length of about 8 to 10 cm, they require a minimum tank size of 40 gallons and should always be kept in schools of at least 6 individuals.

Key Information and Care Requirements

Water Parameters

• Temperature: 22°C to 28°C (72°F to 82°F)
• pH: 6.0 to 8.0
• Hardiness: Very adaptable, thriving in tropical freshwater environments.

Tank Setup

• Substrate: Sand or fine, rounded gravel is essential. Coarse or sharp substrates can easily damage their sensitive barbels (whiskers) as they forage.
• Decor: Provide open areas for sifting the substrate, along with shaded areas using driftwood, rocks, and live plants.

Diet

Emerald Catfish are enthusiastic foragers and predators of small invertebrates. They will readily accept:

• High-quality sinking pellets, granules, and wafers.
• Supplementary live or frozen foods such as bloodworms, brine shrimp, and daphnia.

Behavior and Tank Mates

Emerald Catfish are exceptionally peaceful shoaling fish, making them perfect for community tanks. Ideal tank mates include:

• Small to medium-sized tetras
• Rasboras
• Dwarf cichlids
• Other non-aggressive community fish

Occasionally, they can be seen zipping to the water's surface, as they are capable of intestinal respiration (taking in atmospheric air).

Breeding

Breeding occurs in typical "cory" fashion:

• Females are larger and fuller-bodied, while males are slimmer with more pointed fins.
• Spawning can be triggered by performing large, slightly cooler water changes.
• Adhesive eggs are deposited on plant leaves or glass and hatch after 4 to 5 days.

Coloration

Adults showcase a stunning, metallic emerald-green body with a cream to pinkish underbelly. Juveniles, however, look completely different—sporting a spotted pattern and reddish/orange fins that gradually transition to the metallic emerald color as they mature.
