There are many different types of pets that people can keep in their home.
Some people get them so they can have a companion that they can cuddle with when they live by themselves.
But there are others who prefer something that is easy to take care of and is mainly for decoration - like fish.
Aquariums are large fish tanks that can be very small to hold one or two fish or so large that you might be able to fit in almost seven or eight different types of fish.
There are two different types of aquariums - fresh water and saltwater.
If you are looking to have the more exotic species of fish and corral then you should invest in a saltwater aquarium.
Besides learning how to filter the water and keep the tank clean you also need to know how to properly feed your fish.
Because they are saltwater fish they require different food and need to be fed a specific way.
This will help them to grow and stay alive or at least until one of the larger fish decides to have a snack.
When you purchase the individual fish you need to ask what types of food they eat and how much.
The predator type of fish usually eat meat in large amounts while some others might prefer to eat algae.
Purchase the right type of food and the amount that will last you for a long time.
Some fish are more picky than others and will only eat a specific kind.
You may have to experiment with them and study their behavior and which one they like the most.
When you feed saltwater fish you should only give them enough to allow them to eat it all in five minutes.
The food that is not eaten will break down and dirty up the water.
