How Many Cichlids in One Tank?

Every new African Cichlid keeper asks this question, and it is understandable why. One of the first things we learn when keeping African Cichlids is that overstocking is essential to stopping aggression.

So, the most natural question after that is: How many African Cichlids can I keep in my tank?

While no one can give you a set number, that will work well for everyone. So here we are going to try. But do know that all these numbers in this video are overstocked numbers.

Tank Size and African Cichlids

When keeping an overstocked tank, you'll also have to over-filtrate and perform extra maintenance. This is one of the difficulties that come when keeping African Cichlids. And the main reason why these aren't beginner-level fish, amongst other reasons, of course.

Most beginners do not realize how much maintenance is required in this hobby. Let alone the care that is needed when keeping overstocked fish.

Regarding filtration in this 75-gallon tank, it would be best if you had strong filters. Also, do 80% water changes weekly, keeping everyone happy.

But a 55-gallon is the minimum recommended size for this fish. This is mainly because 55 gallons is the first tank size that gives you the 48-inches swimming length that these fishes need not feel stressed and cramped up.

  • For a 55-gallon tank: 15-20 Peacocks and Haps
  • For a 75-gallon tank: 25-30 Peacocks and Haps
  • For a 125-gallon tank: 50-60 Peacocks and Haps

These numbers are very loose and give and take a few. But, since every tank and fish keeper's farming is different. 

However, if you want to keep a Mbuna-only tank, these numbers can increase a bit because Mbunas are smaller and don't grow to the same size as Peacocks and Haps. So add only 10-12 to the above sets.

On the flip side, these numbers should be reduced if you want to keep a Haplochromis-only tank. Haps are some of the most prominent African Cichlids. To reduce the numbers anywhere from 5 to 10 for each set.

Keeping these overstocked tanks means you'll have to over-filtrate and possibly double the amount of filtration, and you have to be prepared for the required maintenance. Meaning significant water changes and frequent ones. 

Glass cleaning, vacuuming, and filter cleanings are all required when you keep a heavy-stock fish in one tank.
