3. Keep them in a large-size tank.

Cory catfish are peaceful fish and love to live and interact with other peaceful fish in a community tank.

They will thrive living in a community tank with other peaceful fish like neon tetras and guppies.

They require a large enough tank to live and swim comfortably.

Keeping them in a small size tank will make the tank overcrowded, and also, it will affect their growth.

Consider keeping your cory catfish in a minimum size 20-gallon tank.

4. Maintain the appropriate school of your cory catfish.

Cory catfish are schooling fish and prefer to live in a large group of their species.

Keeping them alone or in a small group will make them come under stress and become prone to diseases.

Also, they will start avoiding the food when kept in a small group.

So, consider keeping them in a group of at least 5-6 to form a good school for them.

5. Feed your cory catfish regularly.

Feeding your cory catfish regularly is essential to ensure their faster growth and longer lifespan.

Cory catfish are bottom dwellers and spend most of their time scavenging on the bottom, searching for food.

They will feed on leftovers and other waste like decaying plants and passed away small fish.

However, we should not let them rely only on these leftovers and should feed them with various food to ensure their healthy lifespan.

Cory catfish are omnivore fish that require meat and plant-based nutrition to fulfill their ideal dietary requirements.

Provide them bloodworms, tubifex worms, mosquito larvae, sinking flakes and pellets, brine shrimp, blanched vegetables like cucumber and zucchini, and boiled peas.

Feeding them various types of food containing both plant and meat-based nutrition will help them grow faster and live a longer life.

6. Add plenty of live aquatic plants to your cory catfish tank.

Adding plenty of live aquatic plants to your cory catfish tank will help you make a good hiding spot for your cory catfish.

With a big size tank, they also require plenty of hiding spots to feel safe and comfortable in their tank.

Adding live aquatic plants to your cory catfish tank will create great hiding spots for them and help you keep the water clean.

These are some of the best plants for your cory catfish tank:

  1. Java fern
  2. Micro Sword
  3. Amazon sword
  4. Vallisneria
  5. Lobelia Cardinalis
  6. Blyxa Japonica
  7. Marimo moss balls

You can also consider adding hiding spots like a cave, sunken ships, terra cotta pots, and driftwood to create hiding spots for your cory catfish.

However, plants are the best when it comes to hiding spots. 

7. Avoid overcrowding your cory catfish tank.

An overcrowded tank comes with all these issues:

  1. The tank will get polluted faster than usual.
  2. Your fish will not be able to live and swim comfortably.
  3. There will be a risk of an ammonia spike in your tank.
  4. There will be an oxygen deficiency in your cory catfish tank.

All these will make your cory catfish come under stress and become weak, prone to various diseases and parasites.

So, to ensure that you are not overcrowding your tank, follow the one-inch one-gallon rule. 

The one-inch one-gallon rule means one inch of fish per gallon of water.

Cory catfish can be anywhere between 1-4 inches, with an average size of 2-2.5 inches.

Also, they are schooling fish and prefer to live in a group of at least 5-6 of their species.

So, all this makes a 20-gallon or above tank the idle tank size for your cory catfish.

8. Run proper maintenance of your cory catfish tank.

Monthly maintenance of your cory catfish tank is essential to ensure their longer lifespan.

Performing a water change will not clean the entire tank as some debris and waste get attached to the substrate and at the corner of the glasses.

You have to clean them using your hand and gravel siphon.

Also, cleaning the filter every month is necessary to keep the water chemistry ideal.

Consider cleaning the biofilter media with the aquarium water; for rest, you can use the tap water to clean.

Provide them with soft and good-quality sand as a substrate.

Cory catfish are bottom dwellers and spend most of their time scavenging on the bottom of the tank in search of food.

They use their delicate barbels to search for food and then use their mouth to dig into the substrate and suck the food up.

So, keeping a rough substrate will result in them getting their barbels and skin injured by digging into them.

So, make sure to keep at least a 2-inch soft and good-quality sand as a substrate for your cory catfish.

How long can corydoras live without food?

Cory catfish can live up to 10-12 days without food.

However, we don’t suggest keeping them without food for these long times as it will affect their growth and they will become weak.

Until and unless there is no option left to feed your cory catfish, like you are out for a vacation and there is nobody to feed them, then your corydoras will manage for 10-12 days on their own.

However, you can consider setting up an automatic feeder to feed your cory catfish when you are away and there is no one to feed them.

Just make sure not to place the automatic feeder above anything that causes surface agitation.

Cory catfish are hardy fish and can live in a wide range of water conditions and parameters.
