Overview
The spotted cory is a peaceful catfish that forages over the sandy bottom with its barbels. It is a step up from the easiest fish.
Did you know
The spotted cory is one of several near-identical spotted cories from the western Amazon. It is easiest to confuse with Corydoras agassizii, but it tends to wear many small, evenly scattered spots. Its lookalike carries larger marks set in rows.
Caring for the spotted cory
Keep spotted cories in a group of at least six, in a tank of 20 gal (75 L) or larger. Give them a soft sand bed with open foraging space, plus driftwood, dried leaves and shaded planting.
Keep the water clean and gently filtered, at 70 to 81°F (21 to 27°C) and a pH of 6.0 to 7.5. Regular water changes keep this cory in good condition. Feed sinking pellets, frozen bloodworm and daphnia, and a little wafer, and check that the food reaches the floor.
Spotted cories are peaceful and mix well with small, calm community fish. Reliable aquarium spawning is not well documented for this species.
Good to know
The spotted cory is an armored catfish in the family Callichthyidae. It has a silvery body with a dark blotch in the dorsal fin. Its species name, ambiacus, refers to the Rio Ambyiacu.
In the wild
The spotted cory comes from the Rio Ambyiacu and the neighboring upper Amazon in Peru. It lives over sand in warm, soft, slightly acidic water.
