Best Aquarium Fish for Beginners Guide


If you’re thinking about setting up an aquarium, you’ll probably want to know what kind of fish to get. But it’s not as simple as just choosing a type — there are many different factors involved in selecting the right fish for your new tank. In this guide, we’ll talk about what kinds of things you should think about before making your selection and how to go about finding exactly which aquarium fish are right for you.

There are many fish species available for aquariums.

There are many fish species available for aquariums. You can divide the fish into two groups: freshwater and saltwater.

Freshwater fish species can be divided into three groups: coldwater, warmwater and tropical.

Saltwater aquarium fish are divided into two groups: cold-water and tropical.

Aquarium fish requirements

Fish need a lot of oxygen.

The fish that you keep in your tank require a high level of oxygen to breathe. If the water doesn’t have enough oxygen, the fish will die from suffocation. The amount of air (which contains oxygen) in water depends upon the amount of surface area provided by the aquarium and how much surface agitation there is (such as water movement caused by filters). This can be increased by simply adding more filtration, but it’s best to start with an appropriately sized aquarium for how many fish you want so as not to overcrowd it.Fish need a proper temperature.

Fish are cold-blooded animals which means they can’t regulate their own body temperature like humans do—they rely on environmental factors such as heat or coldness around them to control their internal temperatures. For example: if you put a goldfish in ice water it would die because its body needs warmer temperatures than those found outside of its environment; however if you placed that same goldfish into hot bathwater it would quickly overheat and perish due to lack of protection from external heating sources.

What size aquarium should you buy?

You should determine the size of aquarium you want to buy before you go into the store. Your choice in tank size will be dictated by two factors: how many fish you want to keep and how much space you have available for your aquarium.

If you have only a few goldfish, then an inexpensive 10 gallon tank could work well for them, but if you plan on keeping a lot of different kinds of fish, then it’s best to invest in a larger aquarium with ample room for all different types of fish as well as various plants and decorations. If a large tank isn’t an option because there isn’t enough space where the tank will sit or if money is tight, don’t fret! You can always upgrade down the road when things change financially or when your needs change over time.

Generally speaking though (and without getting too technical), most experts recommend keeping no more than one inch per gallon per day; so keep that in mind when purchasing anything smaller than 20 gallons!

What kind of filters do you need?

Filters are an important part of your aquarium. They remove waste and keep the water fresh, which means you’re not going to have a stinky tank. Filters can be biological, chemical or mechanical (more on those later). If you want a large aquarium (anything over 10 gallons) then you should use an external filter.

Internal filters use the water from inside your tank to filter through a sponge or other material that traps impurities. These are good for small tanks but are not practical for larger ones because they don’t process enough water for them. External filters sit outside of your aquarium and use tubes that lead into it so they take up less room than internal ones do!

Aquarium fish tank maintenance

  • You will need to clean your aquarium at least once a week.
  • You will need to do a partial water change every week or two.
  • You will need to vacuum the gravel every week.
  • You will need to replace the filter media every month or two.

With a little homework and investment, your aquarium will be a great hobby.

With a little homework and investment, your aquarium will be a great hobby.

You can learn a lot about fish, and also about your local ecosystem. Aquariums are peaceful and relaxing; they can be a great way to enjoy nature while you get some quality time with friends and family members.

However, it is important to do your research before buying an aquarium. You should consider the size of the tank based on how many fish you want in it, as well as whether you are willing to change or clean out water for them on a regular basis (bi weekly).


In conclusion, we hope that this guide has given you some insight into how to start your own aquarium. We know it can be a challenge, but with this guide and some research on your part, we hope you’ll be well on your way to having a thriving fish tank in no time!
