Reticulated Corydoras

Reticulated Corydoras (Corydoras reticulatus) displays a remarkably intricate body pattern — the flanks are covered in a fine network of dark lines and spots that create a reticulated (net-like) appearance over a pale silver-cream background. The pattern extends across the head and into the fins, giving the fish a densely patterned look that is genuinely eye-catching in a group.

Feeding & Care Tip: Hikari Sinking Wafers make an excellent daily staple and Sera Vipachips Tropical Wafers are an excellent alternative. Supplement 2–3× per week with Hikari Frozen or Freeze-Dried Tubifex Worms or Hikari Frozen or Freeze-Dried Bloodworms. Feed near the substrate at or after lights-out.

Native to the Amazon basin in Peru and Brazil, Corydoras reticulatus inhabits slow-moving streams and flooded areas with sandy substrate and leaf litter. In the aquarium, soft to medium, slightly acidic to neutral water with fine sand and planted areas replicates its natural habitat well.

Keep in groups of at least six — this is not optional for Corydoras. In the wild these fish occur in schools of dozens to hundreds. A lone Corydoras or a group of fewer than six is a stressed fish that stays hidden, refuses food, and lives a shortened life. In a proper group they are bold, constantly active, and endlessly entertaining to watch as they forage together across the bottom of the aquarium.

Corydoras are highly sensitive to substrate quality — fine sand is strongly preferred over gravel, as rough substrates damage the delicate barbels they use to forage. Regular partial water changes and pristine water quality are essential, as all Corydoras are sensitive to nitrites and dissolved waste. Sand substrate, gentle flow, and shaded areas with driftwood or plants will keep this species at its happiest and most active.
