Luiza Corydoras CW083
Luiza Corydoras CW083 (Corydoras caramater) is a rarely available and highly regarded collector corydoras from Brazil. The pale body displays a large, irregular dark blotch over the shoulder and dorsal region, with additional dark patterning along the flanks. CW083 was the collector number assigned before the species was formally described.
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, Hikari Frozen or Freeze-Dried Bloodworms. Feed near the substrate at or after lights-out when corydoras are most active.
Native to Brazil (Rio Trombetas drainage). In the aquarium, soft to medium, slightly acidic to neutral water with fine sand substrate, gentle filtration, and shaded areas created by driftwood or plants replicates the natural habitat and produces the most active, healthy behavior.
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.
