How to choose your aquarium

Although an aquarium is not technologically complex, there are several factors to consider when choosing the right one for you and your fish:

#1 - The type of fish

Before buying the aquarium, you should decide what type of fish you want to keep in the aquarium. Each species of fish needs specific conditions to thrive. The needs of freshwater fish are obviously not the same as those of saltwater fish. In addition, some fish are extremely delicate and need constant care, while others especially need a lot of space to live a healthy life.

Avoid keeping large fish with small ones, as the larger ones tend to eat the smaller ones. Also, don't keep aggressive breeds with the more peaceful fish, as the latter will be frequently attacked. So always check the fish compatibility chart before putting them together.

#2 - The size of the aquarium

The size of the aquarium is obviously very important. From this will depend the location you need to choose for it, as well as the accessories. Aquariums are measured in liters of contained water, not in physical measurements. But obviously, the more liters an aquarium can hold, the bigger it is. You can find aquariums as small as 3 liters (which we don't recommend, for the sake of the fish) and as large as 300 liters and more, as well as many sizes in between.

As a general rule, when it comes to aquariums, the larger the better. A larger aquarium has room for more fish, but more importantly, the water is less likely to be overloaded with toxins from fish waste in a larger aquarium. For beginners, most experienced owners recommend a 75-100L aquarium. This is because aquariums under 75 l need to be cleaned more often, as they get dirty more quickly, which can be quite difficult for the uninitiated to manage.

#3 - The shape

The traditional aquarium is rectangular. This is also the best choice for the health of your fish, as a rectangular aquarium exposes more water surface to the air, which translates into better oxygenation. But if space or personal preference precludes the use of a rectangular aquarium, you can also find aquariums that are taller than they are wide, aquariums that are cube-shaped, dome-shaped, or even round aquariums.

#4 - The lid

Your aquarium needs a cover to reduce water evaporation, keep your fish from jumping out, and prevent other pets and curious children (or even adults) from fishing in the aquarium. The most basic lids are made of hinged glass and require the use of a separate light fixture. Beginners often prefer hoods, which are lids that incorporate a light fixture to illuminate the tank. Typically, a lighted hood is included with an aquarium kit.

#5 - The location

The final criterion to consider, of course, is location. The best place for an aquarium is one where it can be visible and accessible, but not obtrusive. It should not be in direct sunlight and should be away from doors and windows. Make sure you have such a place before you buy your aquarium. This will save you a lot of hassle.

Don't neglect the accessories

Beware, the tank and the lid alone do not make the aquarium. You also absolutely need other accessories such as a pump (which pushes the water through the filter), a filter (which cleans the water), lighting (because fish need light), heating (because in the fish's natural environment, the water temperature varies between 24 and 26°), tests to check the parameters (to check the water quality, the oxygen level, etc.).

Choose the fish before you choose its aquarium

 class=

In fact, the type of fish you choose will depend on the type of aquarium you need to buy, the setup you need to do and the accessories you need to get. Perhaps the most basic distinction in the world of fish is between freshwater and saltwater species. Regardless of the species you choose, you should do thorough research on any fish you intend to adopt. Pay particular attention to the following:

.

  • What size will the species be? This will help you see if your existing aquarium will be large enough to accommodate it. Or if you are buying an aquarium for the first time, if you have enough space in the house for the size of aquarium needed.
  • What aquarium water parameters are required? Temperature required, pH ranges, light, etc.
  • What types of fish food does it eat? Is it the same or similar to what you already use with your other fish?
  • What is the general temperament of the fish species you want to adopt? Will it get along well with your other fish or those you want to adopt in the future? Will it not attack others or be attacked by others?
  • Is the species known as a prolific breeder? If so, do you have the equipment to keep them or do you have a plan for when the time comes?

Once you have the answers to these questions, you can finally turn your attention to the type of aquarium and its size.

Be responsible

Fish, regardless of species or size, are animals like any other: they need care, attention, affection. Like other small animals, they will wither away if not cared for. And contrary to popular belief, they have a good memory and are capable of learning. Before you adopt a fish, make sure you can provide it with good living conditions.

The different types of aquariums

Freshwater aquariums

This type of aquarium is best for beginners, as freshwater fish make excellent low-maintenance pets. Tropical freshwater fish and cold freshwater fish are much cheaper to buy than marine species. And they are generally easy to please as far as feeding and nutrition are concerned, making them relatively inexpensive to feed. And there are dozens of tropical and cold water fish that can be included in a peaceful and harmonious community setup.

The initial cost of setting up a water aquarium is much less than a saltwater aquarium, as the setup is much more basic. And since you can keep many species of nano-fish in a very small aquarium, this means that you can still enjoy aquaristics even if space in your home is limited. Plus the maintenance of a freshwater tank is pretty basic, requiring only weekly water changes and monthly filter maintenance.

Saltwater aquariums

Saltwater aquariums give you the opportunity to create beautiful waterscapes, made of reefs or themed like a treasure island, etc. And you have a wide variety of fish, invertebrates, corals, anemones and other brightly colored creatures to choose from. However, while beautiful and fascinating to look at, marine fish are generally much more expensive to purchase than freshwater species. They will also be more demanding in terms of food. In addition, they are generally aggressive and it will not be easy to create a harmonious community unless you have a very large aquarium with many hiding places.

Salt water only contains about 80% of the oxygen found in fresh water. This means that you will need a larger aquarium for your fish, as well as a sturdy stand and therefore also the space to accommodate the setup. A marine aquarium generally requires more care: you'll have daily, weekly and monthly tasks to perform to keep the tank in good condition, so you need to be sure you have the time for this level of commitment.

Glass aquarium or acrylic aquarium?

Glass aquarium

Glass aquariums are the traditional choice and are almost always rectangular. Glass aquariums are generally less expensive than acrylic and do not scratch easily, making them a good choice for beginners. However, glass is heavy and can break if dropped or bumped. A glass aquarium can be placed on a stand with support only on the bottom edges, although it is best if your aquarium is fully supported.

This is the most common choice on the market. In fact, all the products in our selection are glass aquariums.

Acrylic Aquarium

Acrylic aquariums come in a wide range of shapes, including square, round, and semi-circular. You will pay more to have an acrylic aquarium, and it won't take long before you scratch it, as acrylic is very prone to damage. Acrylic tanks weigh much less than glass tanks, which is an important factor if you are considering a large tank. Acrylic tanks must be fully supported underneath to prevent them from bending or breaking.

This type of aquarium is most common in breeding and they are harder to find for decorative aquariums: unless you have one custom made, you may not find one in the shape and size you are looking for on the market.

Verdict

Glass or acrylic aquarium, the choice is yours. However, if your main need is for a lightweight aquarium that is easy to move and won't break at the first impact, you should look into acrylic aquariums. Just keep in mind that this type of material turns yellow with time and can become unsightly and there are not many models available on the market. On the other hand, if aesthetics are more important to you, a glass aquarium will be more appropriate. They are certainly more expensive than acrylic aquariums, but there are more models available.

4 reasons to buy an aquarium

Adopting fish as pets can be a rewarding hobby: designing and maintaining your aquariums is a great creative outlet. Watching your fish swim is both relaxing and fun. Fish are great pets because they require less hands-on care than other animals, but they still need your care.

  1. Reduces stress: it's hard to feel stressed when looking at a thriving home aquarium. There's just something so peaceful and calm about an aquarium, taking care of it can help take your worries away.
  2. Boost your creativity: whether you're caring for it or admiring it, an aquarium can help boost your creativity. The visual stimulation of an aquarium in a workplace can help you increase your productivity.
  3. Calming effect for children and Alzheimer's patients: an aquarium can be very soothing, quickly calming moods and minds. This particular benefit has been observed in children with hyperactivity disorders as well as in patients with Alzheimer's disease. In a study conducted at Purdue University, having an aquarium in the home improved mood, alertness and appetite in Alzheimer's patients while reducing aggressive behavior.
  4. Learn responsibility: This is especially true for children. A fish requires less care than a cat or dog, so it's a great way to gently learn about the responsibility of caring for another living being. It teaches children to be responsible for their pets and to do what's best for them, even if they'd rather play or watch TV.

Be sure to check the reputation of the carrier before ordering your aquarium

Before ordering your aquarium online, take the time to check the reputation of the carrier, but also the brand's after sales service, the store's return policy, etc. This is to avoid unpleasant surprises: broken tank, cracked frame, chipped plastic, missing accessories, etc.

Tips

Condition the water

Treat the water with a dechlorinating water conditioner before adding it to your aquarium. Tap water contains chlorine which is harmful to fish. You must therefore treat it beforehand to make it suitable for fish. In addition, remember to change the water regularly to create a favorable atmosphere for your fish to thrive. Finally, don't hesitate to test the water regularly to ensure that your aquarium is not accumulating harmful levels of ammonia, nitrite or nitrate. If necessary, change up to 25% of the water to restore balance.

Clean the filter regularly

The filter is one of the most important pieces of equipment in an aquarium, as it removes all impurities and toxins from the tank. It is essential that the filter be maintained regularly so that it can perform at its best. Use fresh water to clean it, don't use any chemicals, as this will kill the beneficial bacteria that help keep the aquarium environment as healthy as possible healthy for the fish.

Don't overfeed your fish

The more you feed them, the faster they may foul the aquarium with their feces, creating an unhealthy aquatic environment. Not only that, but overfeeding them can lead to serious illness and even death. Establish a proper routine and feed them accordingly. Feeding fish two or three times a day in optimal amounts will help them grow better and keep them healthy.

Monitor the water temperature daily

Count your fish daily and observe them for at least a few minutes to make sure they look healthy. Here are some signs that might alert you to poor fish health: it has abnormal spots or streaks on the body or fins of the fish. It floats near the surface, or swims erratically. It has fins firmly pressed against the body or if it is lying on the bottom of the aquarium.

Check your aquarium thermometer daily and adjust the heating if necessary. Since fish live in a natural environment where the temperature varies very little, it is important to keep the temperature of their aquarium stable for their well-being.

FAQ

How many fish can I put in my aquarium?

This will depend on two factors: the type of fish you want to keep and the size of your aquarium. It is essential to first determine what kind of fish and how many fish you want to put in your aquarium before choosing the size. As a guide, know that a small goldfish needs about 50 l of water to have good living conditions.

What is the best location for my aquarium?

Ideally, your aquarium should be located where you and your family can enjoy it the most, but there are a few other considerations as well. For example, it should be placed near an electrical outlet, as you will need to plug in the filter, light, and heater. Fish need a regular cycle of light and dark, so your aquarium should be reasonably close to a window. However, it should also not be exposed to direct sunlight, as this will promote algae growth and can overheat the water, which can be detrimental to the health of your fish.

Freshwater aquarium or saltwater aquarium? Which is better?

While saltwater fish are generally more colorful, unique and beautiful, these delicate and expensive beauties are often best left to experienced aquarium enthusiasts. The acquisition, setup and maintenance of a saltwater aquarium is considerably more complex than for a freshwater aquarium. In addition, saltwater fish will need a very large aquarium to thrive and be healthy, which can be a problem if you only have a small space.

What other items do I need to set up my aquarium?

In addition to the accessories needed to keep your aquarium running smoothly, think about the decorations inside the tank as well: artificial or real plants, rocks, whimsical decorations such as pretty shipwrecks or treasure chests, and whatever else you like, add character to the tank. But most importantly, provide a place for your fish to hide when they are stressed or feel unsafe. You'll also need adequate food for your fish, as well as a net to easily catch them when it's time to clean the tank.
