Cory Catfish - Tank Size & Conditions

When you get any pet fish, whether a Cory catfish or otherwise, it is very important to provide them with lots of room. Now, something that we do want to mention here is that there is a difference between the recommended tank size for fish and the minimum required tank size.

We are going to talk about all 7 of the species of Cory catfish here, what their minimum tank size needs to be, and what the recommended tank size is. The difference is of course that the minimum tank size is the very smallest amount of room they need to live, whereas the recommended tank size is what is truly ideal for the various types of Cory catfish to be happy and healthy.

1. Bandit Cory Catfish

This type of Cory Catfish can grow to 2 inches or 5 cm in length. It requires a minimum tank size of 10 gallons, with the recommended size being closer to 15 gallons.

They require the water temperature to be between 72 and 79 degrees Fahrenheit, with a pH level between 6.5 and 7, and a water hardness level between 5 and 10 dGH.

2. Bronze Cory Catfish

This type of Cory Catfish can grow to 2.5 inches or 6 cm in length. It requires a minimum tank size of 10 gallons of well, but the ideal tank size is going to be between 15 and 17.5 gallons.

They require the water temperature to be between 72 and 79 degrees Fahrenheit, with a pH level between 5.8 and 7.0, and a water hardness level between 2 and 30 dGH.

3. Julii Cory Catfish

This type of Cory Catfish can grow to 2.5 inches or 6 cm in length, and has a minimum required tank size of 10 gallons. However, the ideal tank size here for the best life is also between 15 and 17.5 gallons.

They require the water temperature to be between 73 and 79 degrees Fahrenheit, with a pH level between 6.5 and 7.8, with a water hardness level between 2 and 20 dGH.

4. Panda Cory Catfish

This type of Cory Catfish will grow to about 2 inches or 5 cm in length. The minimum tank size for these guys is 10 gallons, with the ideal tank size being closer to 15 gallons.

They require the water to be between 68 and 77 degrees Fahrenheit, with a pH level between 6.0 and 7.0, with a water hardness level between 2 and 12 dGH.

5. Pepper Cory Catfish

The Pepper Cory is a slightly larger species, with the females growing up to 3.5 inches or 7 cm in length. They require a minimum tank size of 15 gallons, but the ideal tank size for the best life is going to closer to 20 gallons.

They require the water to be between 72 and 78 degrees Fahrenheit, with a pH level ranging from 6.0 to 7.0, and a water hardness level ranging from 2 to 12 dGH.

6. Skunk Cory Catfish

This type of Cory Catfish will grow to around 2 inches or 5 cm in length. It requires a minimum tank size of 10 gallons, with the ideal tank size being around 15 gallons.

They require the water temperature to be between 72 and 79 degrees Fahrenheit, with a pH level between 6.8 and 7.5, with a water hardness level between 2 and 25 dGH.

7. Three Stripe Cory Catfish

This type of Cory Catfish can grow to 2.5 inches of 5 cm in length. It requires a minimum tank size of 10 gallons, but the ideal size of tank for these fish is going to be between 15 and 17.5 gallons.

They require the water temperature to be between 72 and 78 degrees Fahrenheit, with a pH level ranging from 5.8 to 7.2, with a water hardness level between 5 and 18 dGH.

Therefore, when it comes to how many Cory Catfish you can fit into a 10 gallon tank, the answer is 1. Remember that the Pepper Cory Catfish is a bit bigger and requires a tank of 15 gallons at the least, so you won’t be able to fit even 1 of them into a 10 gallon tank.

Please folks, do keep in mind that for the other 6 species of Cory Catfish, 10 gallons is the absolute minimum, but anywhere from 15 to 20 gallons is what you want to provide them with for their ideal life.


Cory Catfish – Feeding, Tank Setup, Tank Mates, & More

We don’t want to spend too much time on this, but there are some things you should probably know before you get any kind of Cory Catfish. We are going to keep things fairly general here, as most of this stuff applies to all 7 species of Cory Catfish. Let’s just go over some basic housing, care, and feeding tips to get you started.

  • One thing to note here is that all Cory Catfish should be kept in schools of at least 4 or 5. They are schooling fish and will not be happy without some friends to hang out with. Keep in mind that some of the types of Cory Catfish like larger schools, whereas some like smaller schools.

  • Keep in mind that these are very peaceful fish and they often get bullied by larger and more aggressive fish. If you want to keep them with other fish, the tank mates need to be peaceful and non-aggressive.

  • These fish are bottom dwellers and they often like to rummage around in the substrate. It is recommended that you have at least 2 inches of substrate in the bottom of a Cory Catfish tank. You probably want to go with gravel as opposed to sand, but it needs to be rounded and smooth to avoid injury.

  • Cory Catfish can be a bit skittish, sometimes they like privacy, and they like hiding spaces too. For this reason, they tend to do best in heavily planted tanks full of live plants. Some driftwood and rock caves for hiding will make the Cory happy as well.

  • The Cory Catfish does not do well in dirty tanks that do not have good filters. High ammonia and nitrate levels can easily make these fish very sick, to the point of death. A high efficiency filter with all 3 major types of water filtration, one that can handle at least twice the amount of water in the tank per hour, is something you will need.

  • Cory Catfish are bottom feeders and scavengers. They will often eat uneaten food, algae, plant matter, and pretty much everything in between. You should feed them a balanced diet of flakes or pellets. It is best to feed them catfish food. Do not feed them more than they can eat in 5 minutes per day.

Conclusion

The bottom line is that there are many types of Cory Catfish that you can have in your home aquarium. They don’t need a huge tank, but 10 or 15 gallons at the very least (we have reviewed our favorite 10 gallon aquariums here). They are easy to care for, don’t require much in terms of feeding, and don’t need too much maintenance. They are generally considered to be a decent fish to get for first time aquarium owners.
