What is the best tank size for keeping cory catfish?
When it comes to the best tank size for a fish, the key factor that helps us decide is the size of the fish and the number of fish to be kept together.
Cory catfish can be as long as 4 inches in size, depending on the species. However, the average size of a cory catfish lies between 2-2.5 inches.
They are schooling fish and should be kept in a large group of at least 5-6 of their species to form a good school for them.
Some of the space in a tank will be occupied by sand, plants, decors, and other things.
So, keeping in mind all those factors, a 20-gallon tank is the ideal size for a cory catfish.
Consider providing at least a 20-gallon tank or above to your cory catfish to ensure their happy and comfortable living.
Keeping them in a less than 20-gallon tank will end up overcrowding the tank, and they will suffer.
An overcrowded tank will come with issues like deficiency of oxygen, an ammonia spike, and poor water conditions.
