Things to Consider When Choosing the Best Fish Tanks

Purchasing a tropical fish tank is not an easy decision. In fact, it will be years before you have to worry about changing or updating your aquarium and if made incorrectly can cause problems and it will end up in the garage.

To complete our buying guide we will include every factor you need to consider before purchasing your home aquarium. Make sure that the choice you made has been thought carefully by taking these factors into consideration.

Best Fish Tanks

Tank Size

The tank size you choose when starting out in this hobby will depend on a few factors. The most important of these is the number and type of fish that you want to keep. Different fish species have different tank requirements.

Large aquariums have more stocking options but they require more experience, maintenance, and extra equipment. On the other hand, nano aquariums are very limited and due to their small size is difficult to keep water conditions stable and fish alive.

If you are new to this hobby of fish keeping then it is best to start with a medium aquarium until you gain experience. These tanks make it easier to keep the water conditions stable, don’t require extra equipment and you have a lot of stocking options to choose from.

The best fish tanks size for beginners are:

  • 10 gallon fish tank – if you are looking to keep single specie like Betta, Tetras, shrimps, etc together with some plants and aquarium decorations.
  • 20 gallon fish tank – if you want to have a variety of fish speicse and aquatic plants.

Glass vs Acrylic Aquariums

There are two types of fish tanks available on the market. Both of these fish tank materials have their own sets of pros and cons.

Glass tanks are heavier and more difficult to move around. However, they are less likely to scratch and are easier to clean. Glass tanks also allow you to see your fish better and since the material is non-porous, it doesn’t discolor over time.

Acrylic tanks are lighter in weight and easier to move around than glass tanks. However, they are more likely to scratch and show fingerprints. Acrylic tanks also deteriorate over time and can become brittle.

Features

There are many features that companies advertise when they want to sell their fish tank but not all of them are essential. We will list some of the essential features that each modern fish tank must have to be considered an aquarium kit:

  • Built-in lights are essential in a fish tank, to either show the display or even give life to plants and fish. The best fish tank must come with an integrated LED light. The light must be powerful enough to thrive your aquatic plants. If the aquarium kit has a 6000K LED light or up than you are good to go. It is good to have to aquarium light with daylight/moonlight mode as it gives plants and fish natural environments.
  • Filtration system is another essential equipment that must come integrated in your best fish tank. There is no fish that dosn’t need a filter. Eventho you do water changes weekly, fish’s cant life without one. The build-in filter, though basic, may be a more reliable option than purchasing an expensive quality especilly for small aquairums.
  • Heater is a essenntial equipment for your home aquarium. Some tanks are equipped with heaters, though it’s not a common feature in most setups. If you are going to keep fish that reqirue warm temperatures such as Bettas, you would need to get a heater to maintain the temperature of the water. The heater is set inside the tank and keeps the water at a steady temperature so your fish can live healthily and comfortably.

Price

When you are looking for the best fish tanks, it is important to consider the price. Some of the more expensive tanks come with extra features that you might not need or want. The most important factor when deciding on the price of the tank should be the size of the tank.

The best cheap fish tanks are those that are affordable and have a good size for the budget. You don’t want to purchase an aquarium that is too small or too large because it will be difficult to keep and maintain respectively.

If you are looking for a quality fish tank that is affordable, the best option would be Marineland Portrait.

How to Decorate Your Best Fish Tank

When decorating your tank, it’s important to keep in mind the size of the tank and the types of fish you plan on keeping. Some fish prefer more hiding places while others enjoy swimming in an open space. You can use a variety of materials to decorate your tank, including plants, rocks, and driftwood.

If you’re looking for some ideas on how to decorate your tank, here are a few tips:

Theme

Whether you want an underwater ocean theme or a garden theme, choosing a specific style can help you decide which decorations to use. Fish tanks look more attractive when they’re decorated with items that match a theme.

Plants

Plants are a great way to decorate your tank and they also have some practical benefits. Plants help to oxygenate the water and they provide hiding places for fish.

When selecting plants for your tank, be sure to choose ones that are compatible with the types of fish you plan on keeping and your tank size. Some fish don’t prefer plants in their tank on the other hand plants may grow too large for a small tank.

Using live or artificial plants can add some color and interest to the tank. If you are a beginner use plants that are easy to care for. A good example of that is Anubias Congensis. They are popular aquarium plants because they are very hardy and easy to care for.

More experienced aquarists can use Dwarf Baby Tears as a carpet. It will cover the bottom of your tank and provide a place for your fish to hide.

Gravel

Gravel is a good way to add color and a natural look to your fish tank. You can use colored or natural gravel. Just keep in mind that you’ll have to clean the gravel regularly because it will cause water quality problems if it isn’t cleaned out frequently. Also, some fish prefer sand, so be sure to check before using gravel in the best fish tank.

Gravel is a cheap option that provides a nice contrast to plants and other decorations. If you are not sure what type of gravel to go with, it’s always a good idea to go with a neutral color. This will help to ensure that your tank will look good with any type of decoration you choose to use.

Benefits of Having a Home Aquarium

Having a home aquarium is one of the best hobbies you can have. Is like bringing the ocean into your house, and filling your daily routine with joy. No matter if you choose a large or small tank, the benefits are the same. The fish movement in the tank has a meditative effect that will relax you after a busy day. Your house will find peace and serenity.

Aquarium pets are not as noisy or messy as other pets. Your anxiety and stress level will be reduced at maximum. No more fighting with neighbors for noises, or waking up to a messy room. Having an aquarium is having positive vibes around you.

Nowadays the negative feeling of stress and anxiety are higher than ever, and having a home aquarium is a perfect choice. You can either choose a planted tank or a small Betta fish tank to enchant you with its colors and movement. Once you try the relaxation that it brings you, you will want to have it at all costs.

FAQs

If you’re wondering if you need a fish tank heater, or which material is best for your fish tank, read on for answers to these and other questions about home aquariums.

Q: Is a glass or plastic fish tank better?

It really depends on your personal preference. Glass tanks are heavier, but they are also more scratch-resistant than plastic tanks.

Plastic tanks may be less prone to scratches, but they can become cloudy over time and are more likely to develop leaks.

Q: What is the easiest fish tank to maintain?

Fluval Flex is the easiest and most convenient tank to maintain due to its self-cleaning and low maintenance features.

Q: Do I need a heater for my fish tank?

A heater for your fish tank is a must-have. All types of aquatic life require water that’s at just about the right temperature range.

Coldwater fish won’t need one since they’re used to colder environments in their natural habitats. Tropical or marine species do prefer warmer waters; so make sure you have an aquarium heater set in your fish tank

Q: What is the best fish tank for tropical fish?

It really depends on which species you want to keep. Some tropical fish, such as Bettas, like small tanks while others prefer much larger aquariums kits.

The Fluval Edge is one of the best fish tanks for small tropical and marine species since it comes with a heater, light, and integrated filtration. If you want to keep tropical fish that require a large aquarium you can go for Fluval Flex 32.5 gallons. This tank has a powerful Marine 3.0 LED light which is ideal if you want to grow corals.
