Thinking of getting a pet fish? Fantastic! This article looks at the best pet fish for beginners who are new to home aquariums, including some for small aquariums as well as for freshwater and saltwater communities.
Whether it’s for you or someone you love, a pet fish can offer so much in terms of rewarding fun. They also provide a beautiful and serene piece of home décor which helps to promote a calmness whilst bringing joy.
If your pet fish is for a child, this is a great idea and a worthwhile investment. Looking after a fish will teach children responsibility, respect and how to care for something.
And like all pets, a fish gives back the love it receives. Happy and healthy fish will interact with their owners and show a lively personality all of their own.
A pet fish is often thought of as an easy first pet because they are simple to care for and don’t take up much space in the home. You don’t need to walk them or stop them from scratching furniture or shedding all over the carpet.
They are generally considered to be low maintenance and temporary – so if you don’t love fishkeeping as a hobby you can quickly move onto the next thing. While the fish on this list are low maintenance, they aren’t necessarily temporary, and some of these fish will be with you for quite a long time.
Fish are fantastic because they offer a controlled or contained level of maintenance, so won’t affect your whole house.
If you are buying for a child, they do require enough care to teach your child quite a bit in terms of organization and responsibility, and when looked after well can live for many years – so are a very good first pet.
Considerations With Fish For Beginners
Many fish are great for beginners. But you will need to figure out first what size of tank you want to have and if you are going to keep a freshwater or saltwater/tropical aquarium.
You may think that one fish will be easier to start, but most fishkeepers will want to add more to their fish community once they get started. It is easier to start with the size and type of aquarium that you would like to end up with than to just get a little one and then upgrade later.
Here are some questions to ask yourself before you get started with your first pet fish:
- Do you have enough room for the aquarium you’d like?
- How much time can you commit to looking after them?
- Do you know how many fish would you like to have?
- How much money do you have to spend?
Let’s Have A Look At What Makes A Great Fish For Beginners
The best fish for beginners will generally be:
- Happy in a more fluctuating environment, so they don’t mind if the water temperature or pH levels adjust slightly
- Happy with basic food
- Content on their own or friendly in a little fish community
- Not delicate and have stronger immune systems against disease and infection
These fish are cheaper to purchase and easier to find. The tanks, food and materials you need to look after them are also easier to source.
Looking beyond the Goldfish
The goldfish is probably the most famous first pet fish you can get, and for good reason. They are cheap, easy to find, small, hardy and fun. They also grow to be quite large, come in many different looks and live for years.
But we won’t cover the goldfish in this article, because everyone already knows that it’s a great fish for starters.
