What is Cichlid fish?

Cichlid fish is a family of freshwater fish that includes many different species. The most common Cichlids are the African cichlids, which are native to the continent of Africa. There are also Central American cichlids, South American cichlids, and Asian cichlids.

What is the tank size for most Cichlid fish?

For most Cichlid fish, the tank size should be at least 50 gallons. However, bigger is always better when it comes to Cichlids. Cichlids are very active and need a lot of space to swim around. They also produce a lot of waste, so a larger tank will help to keep the water quality clean.

Cichlids are very social creatures and do their best when they are kept in groups. A minimum of six Cichlids should be kept together, but more is always better. They need plenty of hiding places and areas to explore in the tank. Provide them with rocks, caves, hollow tree trunk decor, and plants to create a naturalistic environment.

While most people associate a 75-gallon tank setup with the super expensive tropical fish tank, you can make a great aquarium for fish for much cheaper if you opt for more easily available varieties of fish.

Arrangements to be made while adding Cichlid fish

While adding a Cichlid fish to your aquarium, certain arrangements need to be made to ensure the health and well-being of both the new fish and the existing fish.

  • First, it is important to acclimate the new fish slowly to the water conditions in the fish aquarium. This can be done by slowly adding water from the aquarium to the container that the new fish is in, over about an hour.
  • Secondly, it is important to observe any aggression between the new fish and existing fish. If there appears to be too much aggression, it may be necessary to remove either the new fish or one of the existing fish.
  • Finally, once the new fish has been introduced into the aquarium, it is important to monitor its health closely for any signs of illness or stress.

  1. My plan is to get a 75 gallon tank and put black sand in it along with driftwood and rocks. I plan to get a canister filter. I’m looking at the sicce whale and the fluval, not decided yet. I plan to get a juvenile Jack Dempsey and a juvenile firemouth cichlid. My wife said this will be my Christmas present lol, so I’m just gaining information ahead of time.
    I’ve been considering possible tank mates, still unsure how many is ok, possible options are a convict cichlid or maybe a green terror or an electric blue acara. Maybe one or two of those options.
    I would love to hear any advice and pointers from you all! Thank you.

    • Hi Chad Simcox, usually, thought the Jack Dempsey can be aggressive, it will be just fine with firemouths, and two convict cichlid are their possible tank mates. Every fish has its own temper so you sure keep an eye on they when you introduce them to your tank. I have two convict cichlids in the tank, but they fight with each other every day, but I have two Jack Dempsey cichlid in the other tank and they go well.
      For a 75 gallon tank, the hygger 032 Fish Tank Filter Pump well meet your need, it can increase oxygen for 40–80 gallons of saltwater and freshwater tank.

      Have a nice day
