Is Schwartz's Corydoras suitable for beginners?

It's generally considered beginner-friendly as long as basic water quality is maintained. Because it prefers slightly cooler water, keep an eye on tank temperature.

How many should I keep together?

Since it's a shoaling species, keeping several together is recommended. A small group tends to display calmer, more natural behavior than a single fish.

Can it be kept with other fish?

Yes — its peaceful temperament makes it a good match for other small fish with similar water and temperature needs. It rarely shows aggression toward tankmates.

Adults reach roughly 3.9 to 7 cm, making it a compact species that doesn't need a lot of swimming space.

Are there any legal restrictions on this species?

Schwartz's Corydoras is not subject to CITES.

Schwartz's Corydoras

Schwartz's Corydoras is a small catfish found only in Brazil's Purus River basin, easily recognized by its pale body covered in a fine, net-like pattern of black speckles and a distinctive black-tipped first dorsal spine. Calm and sociable by nature, it does best when kept in a group with others of its kind. This species prefers slightly cooler water than many tropical fish, so a little extra attention to temperature goes a long way. Staying compact at roughly 3.9 to 7 cm as an adult, and generally considered beginner-friendly, it's a great pick for anyone new to keeping Corydoras.

About Schwartz's Corydoras

A small Corydoras from Brazil's Purus River, with a pale, finely speckled body — beginner-friendly and easy to care for.

7 things to know before welcoming a Schwartz's Corydoras

1Keep Them in a Group
Schwartz's Corydoras naturally shoals with others of its own kind. It can survive alone, but keeping a small group lets it display its normal, relaxed behavior with far less stress.
2Prefers Cooler Water
This species does best at water temperatures a bit cooler than many popular tropical fish. If housing it with other species, keep an eye on the heater setting and avoid letting the tank run too warm.
3Use Soft, Fine Substrate
Like other Corydoras, it uses its barbels to sift through the substrate while foraging, and coarse gravel can wear them down over time. Fine, rounded sand is a safer choice for the tank bottom.
4Small and Unobtrusive
Adults stay compact at roughly 3.9 to 7 cm. It won't dominate the tank visually and tends to blend in peacefully alongside other calm tankmates.
5Black Dorsal Spine Is a Key ID
A black-tipped first dorsal spine is the clearest way to tell this species apart from closely related Corydoras. It's worth checking for when you first bring a specimen home.
6Calm and Community-Friendly
Its temperament is peaceful, and it rarely bothers other fish. That makes it a good tankmate for other small species with similar water preferences.
7Prepare the Water First
Before introducing new fish, make sure the tank is fully cycled and the filter is established. Avoiding sudden shifts in water quality reduces stress during the transition.
