Overview
Sychr's catfish is a small, peaceful cory that forages over the sandy bottom with its barbels. It is best with a little experience.
Did you know
Sychr's catfish is a long-snouted cory, yet it is easily muddled with the round-snouted fairy cory, Corydoras atropersonatus. The two swim in the very same river, along with a cluster of other near-identical cories.
Caring for the Sychr's catfish
Keep Sychr's catfish in a group of at least six so they stay confident. A group settles well in a warm tank of 16 gal (60 L) or larger, with a soft sand bed to sift. Add driftwood, dried leaves and shaded planting.
Keep the water clean and gently moving, at 75 to 81°F (24 to 27°C) and a pH of 6.0 to 7.5. Change water regularly to keep these small cories healthy. Feed sinking pellets, frozen daphnia and bloodworm, and crushed wafers, making sure enough reaches the substrate.
Sychr's catfish is peaceful and suits a calm community of small fish that will not crowd the floor. Reliable aquarium spawning is not well documented. Cories of this type lay sticky eggs that the female carries briefly between her pelvic fins, then attaches to firm surfaces.
Good to know
Sychr's catfish is a small armored catfish of the family Callichthyidae. It is finely spotted, with a dark eye mask, and two rows of bony plates armor each flank.
In the wild
Sychr's catfish lives in the Rio Nanay in Peru, a soft, warm tributary of the upper Amazon. The river's water is stained with tannins to the color of tea.
