How to Keep Sterbai Corydoras: A Peaceful, Hardy Bottom-Dweller for Any Tank
Sterbai Corydoras are one of the most sought-after Corydoras species in the freshwater aquarium hobby. Known for their eye-catching white spots, orange pectoral fins, and gentle nature, these bottom-dwelling catfish are a fantastic addition to both community tanks and species-only setups. Their hardiness, sociability, and unique behavior make them especially appealing for beginner and experienced aquarists alike.
Ideal Tank Setup
Sterbai Corydoras thrive in clean, well-oxygenated aquariums with plenty of room to explore. A tank of at least 20 gallons is recommended for a small group, though larger tanks offer more stability and space for natural schooling behavior.
Soft, sandy substrate is ideal to protect their sensitive barbels as they dig and forage. Avoid rough or sharp gravel, which can lead to injury or infection. Provide plenty of hiding spots using driftwood, caves, and dense plant cover. Leaf litter, smooth rocks, and low lighting create a more natural feel that helps Sterbais feel secure.
Sponge filters or gentle canister filters work well. These fish appreciate calm water movement and high oxygen levels, so surface agitation or an added air stone can help.
Water Parameters and Conditions
Sterbai Corydoras are more tolerant of higher temperatures than many other Cory species, making them a good match for warmer tropical tanks. This is especially helpful when housing them with species like discus or rams.
They do best in the following water conditions:
Temperature: 76–82°F (24–28°C)
pH: 6.0–7.5
GH: 2–10 dGH
KH: 1–5 dKH
Keep the water clean with weekly water changes of 25–40%. Avoid sudden swings in pH or temperature, which can stress them or cause illness.
Social Behavior and Tank Mates
Sterbai Corys are peaceful, active, and social fish that should always be kept in groups of at least six. When kept in smaller numbers, they may become shy or stressed.
They make excellent tank mates for most peaceful community fish, including tetras, rasboras, dwarf cichlids, peaceful gouramis, and livebearers. Avoid aggressive or overly large fish that might nip at them or compete aggressively for food.
Their calm demeanor and adaptability also make them a great addition to planted tanks.
Feeding Sterbai Corydoras
In the wild, Corydoras feed on small insects, worms, detritus, and biofilm on the river bottom. In captivity, they thrive on a varied diet of sinking foods and occasional protein-rich treats.
Use high-quality sinking pellets or wafers as a staple diet, and supplement with frozen or live foods like bloodworms, brine shrimp, and daphnia. Blanched vegetables and algae wafers can also be offered occasionally.
Make sure food reaches the bottom where Sterbais can find it—feeding after lights-out can help when housed with more aggressive eaters.
Health and Maintenance Tips
Sterbai Corydoras are generally hardy, but they are sensitive to poor water quality. Keep up with regular water changes and avoid medications or fertilizers containing copper, which is harmful to scaleless fish like Corydoras.
Watch for signs of stress or illness such as lethargy, loss of appetite, or redness around the barbels and gills. Clean substrate and strong biological filtration go a long way in keeping them healthy.
Final Thoughts
Sterbai Corydoras are an ideal bottom-dweller for aquarists seeking a peaceful, striking, and social fish. Their unique coloration and schooling behavior make them a joy to watch, and with the right environment, they’ll thrive for years. Whether you’re building a community tank or a species-focused setup, Sterbais bring both function and beauty to any aquarium.
