Caring for Freshwater Fish
Some people may be of the mind that freshwater fish care is a seemingly non-existent process. However, freshwater fish should not be thought of as a pet that can easily be set up and forgotten about. Fish require a certain amount of care, and as with any pet, only those who are willing to take on the responsibility for another life should entertain the idea of a pet. However, you should consider the fact that pets can be excellent pets for both busy and laid-back lifestyles.
Research is always a great idea when considering a pet–especially fish, as there are SO many types of freshwater fish to choose from. If you’re wanting more than one fish in a tank, be sure to find out whether they are aggressive or not, as some fish will literally kill others in the same tank. It is also wise to understand the environmental needs of your fish, such as tank size, whether it requires freshwater or saltwater, and how often the tank should be cleaned (some fish actually eat the “gunky” build-up on tank walls).
Make sure that you understand the feeding requirements of your fish before you bring them home. Some fish require certain types of food, as well as particular feeding schedules. You should be particularly careful about not over-feeding or under-feeding your fish, as well. If you are undecided about how much food you should give them, don’t hesitate in calling the store or person you bought the fish from–they will most definintely be happy to assist you.
Another job that needs to be done semi regularly is the cleaning of the tank. It is usually recommended that 1/3 of the tanks water is changed monthly. This is to guarantee that the fish are getting a fresh tank to live in.
If you keep these tips in mind when tending to your freshwater aquarium fish, you are sure to have a wonderful experience with your new pet(s).
