Understanding Cory Catfish
Cory catfish are freshwater bottom dwellers that are popular among aquarists for their scavenging behavior and peaceful nature. They are also known as “bottom feeders” due to their tendency to feed on the substrate at the bottom of the aquarium.
Cory catfish come in a variety of sizes, with some species growing up to 3 inches in length while others, such as the pygmy cory catfish, only grow up to 1 inch.
They have a unique feature called “barbels,” which are whisker-like appendages on their mouths that help them locate food on the substrate.
Cory catfish are social creatures and should be kept in groups of at least 3-4 individuals. They make good tank mates for other peaceful freshwater fish.
When it comes to feeding, Cory catfish are omnivorous and will eat a variety of foods. In the wild, they feed on small invertebrates and algae. In the aquarium, they can be fed a diet of sinking pellets, frozen or live foods, and vegetable matter.
It is important to provide a balanced diet for Cory catfish to ensure their health and longevity. Overfeeding should be avoided as it can lead to health problems and water quality issues.
Cory Catfish Diet Fundamentals

Feeding Guidelines
Cory catfish are omnivorous, which means they eat both meat and plants. They are not picky eaters, but it is important to provide them with a balanced diet to keep them healthy and happy.
Beginners should start by feeding their cory catfish a high-quality commercial food that is specifically formulated for bottom-dwelling fish.
These foods come in different forms, such as pellets, flakes, and wafers. It is important to choose a food that sinks to the bottom of the aquarium, as cory catfish are bottom feeders.
Overfeeding can lead to health problems and water quality issues. It is recommended to feed cory catfish once or twice a day, and to only give them as much food as they can eat in a few minutes.
Uneaten food can quickly decompose and release ammonia, which can harm the fish and other inhabitants of the aquarium.
In addition to commercial food, cory catfish can also be fed live or frozen foods, such as bloodworms, brine shrimp, and daphnia. These foods should be offered as a supplement to their regular diet, and not as a replacement.
It is important to consider the community of fish in the aquarium when feeding cory catfish.
They are peaceful fish that get along well with most other species, but they may have competition for food if there are other bottom-dwelling fish in the tank. It is recommended to feed cory catfish first, and then offer food to other fish.
Breeding Cory Catfish and Fry Food
Breeding cory catfish can be a rewarding experience, but it requires careful attention to their dietary needs. Providing the right food for both the adult fish and their fry is crucial for their health and growth.
During breeding, it is important to ensure that the adult fish are well-fed and have a varied diet. This can include a combination of high-quality pellets, frozen or live foods such as bloodworms, brine shrimp, and daphnia.
Feeding the adults a variety of foods will help ensure that they are in optimal condition for spawning.
Once the eggs have been laid, they will hatch into fry. At this stage, it is important to provide the fry with the appropriate food.
Newly hatched brine shrimp is a popular choice for feeding cory catfish fry, as it is high in protein and easily digestible. Infusoria, which are tiny aquatic organisms that can be cultured at home, can also be used to feed the fry.
As the fry grow, their dietary needs will change. They will require more protein and nutrients to support their growth.
At this stage, it is important to provide them with a varied diet that includes high-quality pellets, frozen or live foods such as bloodworms, brine shrimp, and daphnia.
Guide on How to Pick Food For Cory Catfish
Cory catfish, as bottom feeders, search the base for worms, larvae, and vegetable matter. So when picking their food, it is best to choose foods with similar quality and contain more proteins.
Follow the steps below to gather food for your Cory catfish
1. Pay Attention to The Ingredients
Some hobbyists use tetra food to feed the Cory catfish, but this seems to decline the health because Cory catfish are delicate slowly. As such, when picking their food, you must pay utmost attention to the ingredients. Check the package for information on the formula composition.
2. Avoid Poor Quality Ingredients
Despite Cory catfish being the same species, they have different tolerance levels. Hence, there are several ingredients you must avoid if you want to prevent your cories from having any health issues.
In general, don’t feed your fish with fish meals with poor-quality ingredients. Poor-quality fish meals mainly contain leftovers such as bones, scales, and skin. These leftovers contain zero nutrients and add zero or no value to your Cory catfish diet.
Another example of poor quality ingredients is terrestrial grains, and Catfish Cory can’t digest them. Due to their inability to digest these grains, they will spit them out, which will result in more waste and high levels of ammonia in the water. To be safe, below is a list of ingredients you must not feed your cories.
- Wheat
- Soy
- Synthetic vitamins
- Preservatives
- Corn
- Food coloring
- Rice
3. Sort After High-Quality Ingredients
When you set aside the subpar ingredients mentioned above, there are a handful of high-quality ingredients that your corydoras would love. Here are a few
- Kelp
This seaweed provides your Cory catfish with superb anti-inflammatory benefits that help enhance their immunity against diseases such as dropsy, ich, and fish rot.
- Black Soldier Fly Larvae
Black soldier fly larvae are a high-quality food ingredient for your Cory catfish. This fly’s larvae are very proteinous, and their exoskeletons are soft and can be easily digested compared to insects with hard exoskeletons.
- Krill
Krill is an excellent protein and omega-three fatty acid source with low fat.
Cory Catfish Tank Mates
Cory catfish are peaceful and social creatures that can coexist with a variety of other fish species. However, it’s important to choose the right tank mates to ensure a harmonious and stress-free environment for your cory catfish.
Good Tank Mates for Cory Catfish

- Tetras (such as neon tetras, ember tetras, and cardinal tetras)
- Rasboras (such as harlequin rasboras and chili rasboras)
- Guppies
- Platies
- Swordtails
- Mollies
- Endlers Livebearers
- Dwarf Gouramis
Plecos as Tank Mates for Cory Catfish
Plecos are a popular choice as tank mates for cory catfish because they are also peaceful and non-aggressive.
However, it’s important to choose the right type of pleco to avoid any potential problems. Some good plecos to keep with cory catfish include:
- Bristlenose plecos
- Rubberlip plecos
- Clown plecos
It’s important to note that some larger pleco species can be aggressive and territorial, which can stress out your cory catfish. Always research the specific species of pleco before adding it to your tank.
Algae Eaters as Tank Mates for Cory Catfish
Cory catfish are not known for their algae-eating abilities, so it’s a good idea to add an algae-eating fish species to your tank to keep it clean. Some good algae-eating fish to keep with cory catfish include:
- Otocinclus catfish
- Siamese algae eaters
- Nerite snails
- Amano shrimp
It’s important to note that some algae-eating species can be aggressive towards cory catfish, so it’s important to choose the right species and monitor their behavior closely.
Understanding Water Conditions for Cory Catfish
Cory catfish are freshwater fish that require specific water conditions to thrive. Understanding the water conditions that cory catfish need is essential to keeping them healthy and happy.
One of the most important water parameters to consider is the pH level. Cory catfish prefer a pH level between 6.0 and 7.5, with a neutral pH of 7.0 being ideal.
It is important to monitor the pH level regularly to ensure that it remains within this range. If the pH level is too high or too low, it can cause stress and health problems for the fish.
In addition to pH, the hardness of the water should also be considered. Cory catfish prefer soft to moderately hard water, with a hardness level between 2 and 15 dGH.
Water that is too hard can cause health problems for the fish, while water that is too soft can be acidic and cause pH fluctuations.
It is also important to consider the temperature of the water. Cory catfish prefer water that is between 72 and 78 degrees Fahrenheit. Keeping the water temperature within this range will help to ensure that the fish remain healthy and active.
When setting up a tank for cory catfish, it is important to cycle the tank before adding any fish. This process allows beneficial bacteria to grow and establish in the tank, which helps to keep the water clean and healthy for the fish.
