Hognosed brochis
Introduction
The Hognosed Brochis, scientifically known as Brochis multiradiatus, is a captivating freshwater catfish cherished by aquarists for its unique appearance and peaceful demeanor. Distinguished by its elongated snout, this species adds both visual interest and dynamic activity to community aquariums. Its hardy nature and relatively straightforward care requirements make it an excellent choice for both novice and intermediate fishkeepers.
What makes the Hognosed Brochis stand out in a home aquarium?
Its distinctive "hog-nosed" profile and shimmering greenish-brown coloration set it apart, providing a unique aesthetic appeal.
Is the Hognosed Brochis suitable for beginners?
Yes, its peaceful temperament and adaptability to various tank conditions make it well-suited for those new to fishkeeping.
Care and Environment
Proper care of the Hognosed Brochis involves replicating its natural habitat to ensure health and longevity. A minimum tank size of 120 liters is recommended to accommodate a small group, as these fish thrive in social settings. For optimal conditions, especially when housing larger groups or additional species, a tank of 200 liters or more is ideal.
Water parameters should be maintained within the following ranges:
- Temperature: 21°C to 26°C
- pH: 6.0 to 7.5
- Water Hardness: 2 to 12 dGH
Efficient filtration is crucial to keep the water clean and well-oxygenated. Regular water changes, approximately 20-30% weekly, help maintain water quality and reduce nitrate buildup. Lighting should mimic a natural day-night cycle, with moderate intensity to support any live plants and provide a comfortable environment for the fish.
When it comes to feeding, the Hognosed Brochis is omnivorous and primarily forages along the tank bottom. A balanced diet includes high-quality sinking pellets or wafers, supplemented with live or frozen foods such as bloodworms, brine shrimp, and daphnia. Occasional vegetable matter, like blanched spinach or zucchini, can also be offered.
The tank should feature a soft, sandy substrate to protect the fish's delicate barbels, which they use to search for food. Incorporating hiding spots with driftwood, caves, and sturdy plants like Java Fern or Anubias provides security and mimics their natural environment. Ensure that any plants are well-anchored, as these fish may inadvertently uproot them while foraging.
How many Hognosed Brochis should be kept together?
They are social fish and should be kept in groups of at least 5-6 individuals to promote natural behaviors and reduce stress.
Can Hognosed Brochis be kept with other fish species?
Yes, they are peaceful and can coexist with other non-aggressive species that share similar water parameter requirements.
What type of substrate is best for Hognosed Brochis?
A soft, sandy substrate is ideal to prevent injury to their sensitive barbels during foraging.
Origin and Habitat
Native to South America, the Hognosed Brochis inhabits slow-moving rivers and floodplains, particularly in regions like the Rio Lagartococha. These environments are characterized by soft, sandy substrates and abundant vegetation, providing ample hiding spots and foraging opportunities. The water in these habitats is typically warm, slightly acidic to neutral, and well-oxygenated, conditions that should be mirrored in the home aquarium to ensure the well-being of the fish.

What are the natural water conditions of its habitat?
The natural habitat features warm, slightly acidic to neutral, and well-oxygenated waters with soft, sandy substrates.
Temperament and Compatibility
The Hognosed Brochis is known for its peaceful and sociable nature, making it an excellent addition to community aquariums. It thrives in groups and should be kept with at least 5-6 of its kind to encourage natural schooling behavior and reduce stress. Suitable tank mates include other peaceful species that occupy different levels of the aquarium, such as tetras, rasboras, and small gouramis. It's advisable to avoid housing them with aggressive or significantly larger fish that might intimidate or prey upon them.
Is the Hognosed Brochis aggressive?
No, it is a peaceful species that coexists well with other non-aggressive fish.
What are suitable tank mates for the Hognosed Brochis?
Compatible companions include tetras, rasboras, and small gouramis that share similar water parameter requirements.
Why is it important to keep Hognosed Brochis in groups?
They are social fish that exhibit natural schooling behavior, which helps reduce stress and promotes overall health.
Interesting Facts
The Hognosed Brochis possesses several intriguing traits that captivate aquarists. Notably, it has the ability to breathe atmospheric air by gulping at the water's surface, thanks to a specialized, highly vascularized intestine. This adaptation allows it to survive in low-oxygen environments. Additionally, when threatened, it can lock its dorsal and pectoral fin spines into position, which can cause a painful "sting" if handled improperly. Therefore, caution is advised when netting or handling these fish.
How does the Hognosed Brochis breathe atmospheric air?
It utilizes a specialized intestine to absorb oxygen from the air, allowing it to survive in low-oxygen conditions.
What defensive mechanism does the Hognosed Brochis have?
It can lock its dorsal and pectoral fin spines to deter predators, which can cause a painful sting if handled improperly.
