Brochis pulwartzi – Peaceful Corydoras-Type Catfish for Community Aquariums

Brochis pulwartzi is a rare and peaceful South American catfish with armored plating and elegant whiskers, perfect for planted and community aquariums.

🌿 Species Overview

• Scientific Name: Brochis pulwartzi

• Common Name: Pulwartz’s Brochis, Armored Catfish

• Origin: South America (Peru, Brazil, Amazon Basin tributaries)

• Habitat: Slow-moving blackwater and clearwater streams with sandy or muddy substrates

• Temperament: Peaceful, social, and non-aggressive

Brochis pulwartzi is an attractive armored catfish closely related to Corydoras species, prized for its active bottom-dwelling behavior, elongated dorsal fin, and elegant armored body. It is ideal for calm community aquariums where it can forage naturally.

🎨 Appearance & Coloration

• Elongated, armored body covered in bony scutes

• Metallic silver to light bronze base coloration

• Elegant long dorsal fin, often taller than most Corydoras

• Transparent to lightly tinted fins

• Barbels (whiskers) used to detect food in substrate

The combination of tall dorsal fin and active foraging makes Brochis pulwartzi a visually captivating addition to the bottom of the tank.

📏 Size & Lifespan

• Adult Size: 7–10 cm (2.5–4 inches)

• Lifespan: 5–8 years with proper care

This catfish is slightly larger than typical Corydoras, requiring a tank with ample swimming and foraging space.

💧 Water Conditions

Brochis pulwartzi thrives in soft to moderately soft water conditions:

• Temperature: 23°C – 28°C

• pH: 6.0 – 7.5

• Hardness: 2–12 dGH

• Water Flow: Gentle

• Filtration: Sponge or canister filter

• Environment: Planted or driftwood-rich aquariums with sandy substrate

Soft sand or fine substrate prevents damage to barbels and encourages natural foraging.

🏡 Tank Setup Recommendations

• Minimum Tank Size: 20 gallons (for a small group of 5–6)

• Substrate: Fine sand preferred

• Lighting: Moderate

• Plants: Java fern, Anubias, Cryptocoryne, floating plants

• Decor: Driftwood, leaf litter, rocks, and caves

They appreciate open areas for swimming along with shaded or planted retreats for comfort and security.

🐟 Tank Mates Compatibility

Brochis pulwartzi is highly peaceful and works well in community tanks with other gentle species.

Compatible Tank Mates:

• Small tetras (neon, cardinal, ember)

• Rasboras

• Small peaceful Apistogramma species

• Other peaceful catfish (Corydoras, Otocinclus)

Avoid:

• Aggressive cichlids

• Large predatory fish

• Fin-nipping species

Best kept in groups of 5 or more to encourage natural shoaling behavior.

🍽 Feeding Habit

• Omnivorous bottom-dweller

• Diet Recommendations:

  • Sinking pellets or wafers for catfish

  • Frozen foods: bloodworms, brine shrimp, tubifex

  • Live foods: daphnia or blackworm

  • Occasional blanched vegetables (zucchini, cucumber)

Feed small portions 1–2 times daily. Brochis pulwartzi actively sifts substrate in search of food, so provide sufficient coverage for natural foraging.

🛠 Care Level

• Difficulty: Beginner to Intermediate

• Hardy and peaceful species

• Sensitive to poor substrate (rough gravel can damage barbels)

• Suitable for aquarists new to South American catfish

Weekly water changes (20–30%) and maintaining a sandy substrate will ensure health and longevity.
