Hoplisoma Noxium CW155 – Rare Dark Corydoras-Type Catfish

Hoplisoma Noxium CW155 is a striking and rare Corydoras-type catfish identified by its CW155 designation, prized by aquarists for its dark, uniform coloration and peaceful nature. This bottom-dwelling fish is perfect for planted aquariums, nano tanks, and community setups due to its small size, calm temperament, and active foraging behavior.

The “Noxium” line is known for its deep charcoal to almost black body color, sometimes with subtle patterning on the fins and body. This unique dark appearance contrasts beautifully with green plants, light substrates, and driftwood, creating a natural and elegant aquascape.

Like other Hoplisoma species, CW155 is a social and schooling fish. They are most active when kept in groups of at least 5–6 individuals, often swimming together along the bottom, sifting through the substrate for food. Their sensitive barbels help them detect small food particles, contributing to a cleaner tank environment.
