Overview

October 16, 2026 · Suggest an edit

Brochis multiradiatus is a close relative of the emerald corydoras (Brochis splendens) and, like it, carries a metallic green–bronze sheen. It is distinguished by two clear features: its long, pointed snout (the source of the name "hognose") and a very long dorsal fin of 17–18 rays that runs along the back. Its scientific name also describes this "many-rayed" fin. Adults reach 8–9 cm. It comes from the Napo basin of Ecuador and Peru and is found in the trade far less often than the emerald corydoras.

Tank Setup

October 16, 2026 · Suggest an edit
  • At least 120 liters for a group of 5–8; a large footprint.
  • Very fine, soft sand substrate; it digs deep into the sand with its long snout.
  • 22–26°C, soft to moderately hard, clean and well-oxygenated water.
  • Regular water changes and a mature aquarium.

Diet

October 16, 2026 · Suggest an edit

Sinking tablets and granules, frozen bloodworms, tubifex and brine shrimp. It searches for food buried in the sand with its snout; a diet supplemented with frozen food suits it well.

Behavior and Compatibility

October 16, 2026 · Suggest an edit

A peaceful, calm bottom dweller; it sifts the bottom in a group. Despite its size, it leaves fish and shrimp alone.

Good companions: medium-sized tetras, peaceful barbs, gouramis, angelfish, dwarf cichlids, other corydoras.

Avoid: aggressive cichlids that claim the bottom, large predators, sharp substrate.
