Cichlids: Freshwater Fish

Information about the freshwater fish known as the Cichlid.

Cichlids are not extremely hard to keep alive. They are somewhat easy if you know the basics of keeping fish. You need a good filter system which over filters the tank, and a bubbler. You will need the correct type and size of gravel. Buy small gravel that wont get stuck in the fishes mouth. You can purchase live plants which you bury in the rock. You can place these in a tank with any type of rock, it does not have to be gravel.

Cichlids are omnivores and they will eat flake food as well as frozen food. You can buy freshwater variety packs at www.petland.com. You can also buy frozen food online from Dr Fosters and Smith. They have a good supply and they have low prices also.

Cichlids come in every color imaginable which is why people buy them. They look great in a tank but it has to be a large tank which can house each fish. For specifics on each fish that you buy you can go to www.liveaquaria.com and see the ph, temperature and other requirements. Cichlids usually require a temperature around 78 to 80 degrees. This means that you will have to buy a heater because normal temperature for a tank is about 75 degrees.

Cichlids in the wild are found around South America. They can be found swimming around with alligators, hippos, and other large animals. They are found in very large numbers, usually thousands of fish. With thousands of different colors, you can imagine what a scene that would be to see all the fish swimming around together. Some zoos actually have cichlid displays. They are often a popular sight among people who visit the zoos.

I would suggest buying a cichlid if you can afford a large tank, unless it's a small variety of cichlid.
