Overview

October 16, 2026 · Suggest an edit

The reticulated corydoras is recognized by the dark, net-like pattern spread over a pale gray background, especially on the head and back; its scientific name also means "net-like." Its fins are spotted as well. Adults reach around 6 cm. It is often confused in stores with the very similar-looking C. sodalis; care conditions are the same for both species. Like other corydoras, it can breathe air through its gut and now and then darts to the surface.

Tank Setup

October 16, 2026 · Suggest an edit
  • At least 60 liters for a group of 6–10.
  • Fine, rounded sand substrate; shaded areas with roots and plants.
  • 22–26°C, soft to moderately hard, clean and well-oxygenated water.
  • Regular water changes (25–30% a week) and a mature aquarium.

Diet

October 16, 2026 · Suggest an edit

Sinking tablets and granules, frozen bloodworms, brine shrimp and daphnia. Because it searches for food on the bottom, do not let fast midwater fish grab the food first; evening feeding helps.

Behavior and Compatibility

October 16, 2026 · Suggest an edit

A calm, peaceful bottom dweller; it roams in a group, sifting through the sand. It leaves shrimp and small fish alone.

Good companions: tetras, rasboras, dwarf cichlids, gouramis, otocinclus, shrimp, other corydoras.

Avoid: aggressive cichlids that claim the bottom, large predatory fish.
