Getting a new pet can be a fun and rewarding experience, but not all pets are created equal. A “regular” pet like a cat or dog means picking up bowls for food and water, maybe a pet bed as well as a collar and leash for walks. When you decide you want a pet fish, there’s much more preparation involved since you not only need to purchase the same kinds of things as for a house pet as well as a whole slew of other items to provide the natural living environment for a fish.
The first thing you need to look at is the variety of saltwater or fresh water aquariums for your fish. Some fish thrive in a saltwater environment while others can only survive in fresh water aquariums. You also need to make sure that your aquarium tank is large enough to house all of its inhabitants. Too many or conflicting species of underwater life can result in a dangerous and unhealthy environment for your fish which can easily lead to illness or death without proper planning and care. You don’t have to worry about giving your fish too much space, but not enough space (something you need to look at when adding new fish to an existing environment as well) can be a serious problem.
