So you are planning to set up a saltwater aquarium at home and you are in the planning stages of deciding what type of fish to buy. Since the well-meaning people who work in pet stores are not always trustworthy as they may not be very experienced, do your own research.
One thing to keep in mind is that saltwater fish can be very expensive. This is one of the most obvious reasons why you really need to plan your fish before buying it. You also need to buy appropriate red sea salt for your aquarium to keep saltwater fish.
Here are some things you may or may not think about.
In the world of fish, size matters. When you want to get really big fish and you need to consider that you need a big tank. Larger fish require more freedom of movement and tend to eat more than smaller fish.
When you consider the size of your fish in the size of your tank, you have a general idea of how many fish you can hold. Overfilling the tank can stress all of your fish, making them more susceptible to disease and other ailments due to stress and poor military conditions.
What your fish eat is another important consideration. Some fish are carnivorous, some are herbivorous, and others are anything, including smaller fish. This is one reason why you should think twice about mixing large and small fish in the same aquarium.
Small fish are usually convenient food for large fish. To further complicate matters, some fish like to be on the surface while others are bottom eaters. You have to choose fish that are compatible with each other in terms of their eating habits, otherwise, your care will become much more complicated.
