Overview

The long nosed arched cory is a larger, peaceful cory that shoals over sand in a community tank. It is best for a keeper who has kept a few fish already.

Did you know

The long nosed arched cory uses its extended, slightly down curved snout as a probe. It digs further into the sand for buried food than its blunt nosed relatives can reach.

Caring for the long nosed arched cory

Keep long nosed arched cories in a group of at least six. Their size and need for company call for a tank of 30 gal (115 L) or larger. Give them a soft sand bed so the long snout and barbels stay healthy, with driftwood, leaf litter and shaded planting.

Keep the water clean and gently filtered, with regular changes. Aim for 73 to 77°F (23 to 25°C) and a pH of 6.0 to 7.5. Feed sinking pellets, frozen bloodworm and other meaty foods, and the odd wafer. Make sure enough reaches the floor.

Long nosed arched cories are peaceful and mix well with calm, medium sized community fish. Reliable aquarium spawning is not well documented. Long snouted cories lay sticky eggs onto firm surfaces after a brief pairing.

Good to know

The long nosed arched cory is an armored catfish of the family Callichthyidae, listed as Corydoras narcissus. It is one of the long snouted cories, with an elongated, slightly arched head. Two rows of bony plates armor each flank.

In the wild

The long nosed arched cory comes from the Rio Purus in the Brazilian Amazon. It lives over sand in warm, soft, slightly acidic water.
