Coast Corydoras
Coast Corydoras (Scleromystax prionotus) is a rare and beautiful species from coastal Atlantic drainages of southeastern Brazil. The robust body displays a complex pattern of dark blotches and spots on a pale background, with males developing distinctive facial bristles similar to the related Barbatus Corydoras — though less dramatically colored. It is rarely seen in the aquarium hobby, making it a genuine collector's prize.
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 Bloodworms. Higher-protein supplemental feeding supports male facial development.
Native to coastal Atlantic drainages of southeastern Brazil — a subtropical species that prefers cooler conditions than most tropical corydoras. As with Scleromystax barbatus, it requires cleaner, cooler, well-oxygenated water.
Keep in groups of at least six. Males can be mildly territorial but are peaceful with other species. Completely peaceful with all non-predatory tankmates. A rare find worth showcasing in a species-specific or carefully planned community setup.
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.
