Sterbai Cory Care
Sterbai Corys are a popular fish, and they are often chosen for home aquariums due to their striking markings. They have a black colored body with white spots dotting them all over. They have sharply pointed fins and flat bellies. Sterbai Cory have barbels on their mouths.
These barbels are like their taste buds; they use them to feel along the bottom for food. Barbels appear like little whiskers that protrude from the bottom sides of their mouths. These barbels are important as they help the fish find food in murky water.
It is almost impossible to tell the difference between males and females until they reach maturity. When viewed from above, a grouping of Sterbai Cory will show that the females appear to be more rounded than the males.
Sterbai Cory Food & Diet
Sterbai Cory are omnivorous, and they do best with a varied diet. You will notice Sterbai Cory spend most of their time scavenging along the bottom of the tank and scooping up the bits of food their tank mates leave behind. Even though they efficiently clean up what is left behind, Sterbai Cory will still need their diet supplemented. They should only be fed high-protein foods about once a week.
Sterbai Corys are more active in the evening, so it is best to feed them during this time. It is possible to overfeed these fish, so you will want to feed them only enough food so they can completely consume it in 2 to 3 minutes.
It is important to observe these fish during feeding time, especially if they are being housed in a community tank. Sterbai Corys feed on the bottom of the tank, so you will want to ensure that the other fish aren’t consuming all of their food before it hits the substrate.
Sterbai Cory Size & Lifespan
Sterbai Cory will reach 2.5 inches in length at full maturity. Some cases have even been growing as long as 4 inches, but that is rare. This small size makes them a popular choice for those with limited space for an aquarium.
The Sterbai Cory can live 15 to 20 years when properly cared for. Keeping them in a clean, stress-free environment is key to their longevity.
Tank Size & Tank Requirements
Sterbai Corys should be kept in a group of at least 4 to 6. They should be housed in a tank that is at least 20 gallons. The more Sterbai Corys you plan on keeping together, the larger the tank will have to be to accommodate their scavenging behavior.
Sterbai Cory Tank Setup
Setting up a tank for Sterbai Cory, you will want to consider the substrate carefully. Sterbai Cory are scavenging fish that spend most of their time along the bottom of the tank looking for food. They use their barbels, which are taste bud-like organs that the fish use to find food. Rough edges of the tank or rough substrate could potentially damage these sensitive organs.
You will want to choose a fine sandy substrate for their tank. It is important to use decor to give the Sterbai Cory places to hide. Driftwood, plants, and rocks to create shaded spots for them. Floating plants would also be good for them since they aren’t occupying the space at the bottom of their tank.
Sterbai Cory spend their time at the bottom of the tank, so it is a must to make sure that they have enough space to roam the bottom of the tank.
How Many Sterbai Cory Can You Keep in a 10 Gallon Tank?
Some keepers of Sterbai Cory suggest that you can keep them in a 10-gallon tank, but it is not an ideal setup for them. Sterbai Cory must be kept in a grouping of 4 to 6, requiring them to be housed in at least a 20-gallon aquarium. If you want to keep them in a community tank, you will want to provide them with a minimum of a 50-gallon tank.
Sterbai Cory Tank Mates
The most compatible tank mates for the Sterbai Cory are other Sterbai Corys. These fish do best when they are in a group of at least 4 to 6.
Sterbai Corys can be kept with the more aggressive Betta fish since they will not get in their way or challenge them for food or space.
It is possible to keep almost any species of fish along with your Sterbai Corys as long as they share the same water parameters. You will want to avoid keeping them with any other larger, bottom-dwelling fish, such as Oscars and some Cichlids. Non-compatible fish could harass and stress out your Sterbai Corys and potentially make them ill or kill them.
Sterbai Cory and Shrimp
Sterbai Corys make great tank mates for Shrimp. Even though Sterbai Corys may eat some of the Shrimp juveniles. It will not be a significant enough amount, and you will still notice your Shrimp population increasing.
Sterbai Cory Breeding
If you are planning on breeding Sterbai Cory, you will want to provide them with a separate breeding tank. It is not difficult to get them to breed, as they will readily do so in captivity. You will want to place the bonded pair in the breeding tank.
A key to getting these fish to spawn is ensuring that the water parameters are right and that you perform regular water changes. Making partial water changes to cool the temperature in the breeding tank to lower the temperature will likely trigger these fish to spawn.
When the female is ready to spawn, she will place her eggs between her fins, and the male will wrap them around her and the eggs to fertilize them. It is often referred to as a T shape. Once the eggs are fertilized, the female will place the semi-adhesive eggs onto plants, decor, or even the sides of the tank. The female and male will repeat this process a few times.
After the eggs have been fertilized and placed, the parent fish will need to be removed from the breeding tank to help the survival of the fry. Once the fry is free swimming, they do not require help from the parents.
How Long Does it Take for Sterbai Cory Eggs to Hatch?
Sterbai Cory eggs take around 5 days to hatch and roughly 96 hours to become free swimming after that.
Sterbai Cory Growth Rate
Sterbai Corys grow fairly fast in the first 3 to 4 months of their lives. You can expect these fish to reach their sexual maturity at around 6 to 9 months old, but they should not be bred until they are around 2 inches in length.
Sterbai Cory Disease
Sterbai Cory are considered hardy fish, but they are still susceptible to many of the same ailments as all freshwater fish. These fish often suffer from damaged barbels, bacterial infections, and fungal infections. The key to keeping these fish healthy is providing them with the appropriate setup, a clean home, and a stress-free environment. Added stress to these fish will lower their immune system and make them susceptible to sickness.

Sterbai Cory vs. Julii Cory
Sterbai Cory (Corydora Sterbai) tend to be slightly larger at full maturity than the Julii Cory (Corydoras Julii). Both have similar temperaments and shoaling habits, but you will notice these fish not mingling species in a community setup. Instead, you will notice them sticking to their own group but cohabiting peacefully with one another. It can be difficult to tell these two fish apart because they are so similar in markings and behavior.
The Sterbai Cory has a white dotted look on its darker body, and the Julii Cory has dots too. However, the dots on the Julii Cory appear connected rather than separate, like in the Sterbai Cory.
