How To Choose The Best Fish Tank If You’re A Beginner?

When choosing a fish tank, you need to select the right tank size, the type of fish, the plants, and the equipment. If you want to keep fish as pets, the bigger the fish tank, the better. A 10-gallon aquarium is excellent, but anything 20-gallon or more is ideal.

It’s easier to keep the water conditions in a large tank stable than in a small tank. Larger fish tanks can also hold more fish. Larger aquariums also let you easily fit different equipment and decorations into the tank.

To make it easier, you should buy an all-in-one kit so that you can have lighting and a filter. Some fish tank kits have a heater, thermometer, fish net, fish food, and tank decor.

The Size Of The Tank

Small fish like guppies can thrive in a small aquarium, but for larger fish, you will need a big tank. When buying an aquarium, think about the type of fish you plan to keep. Think about the different types of plants. How big do the fish or plants grow? The size of the aquarium is an integral part of choosing the right tank size. You want to pick a tank that will allow all your pets and plants to thrive and be happy.

The Placement Of The Tank

Before you rush off and buy the bigger fish tank, think about where you’re going to put it. Will it fit in that location? Will it be in direct sunlight? Fish tanks should never be in direct sunlight as it promotes algae growth, and you don’t want that!

Once you have a decent spot to place your fish tank, take some measurements to know what size tank can fit the space. Once you know what size you can accommodate, you can determine what kind of fish you can keep and how many.

Consider The Weight

Think about what you plan to place the fish tank on. Is the stand strong enough to bear the weight of the aquarium when it’s full of water? Some aquarium stands are built specifically for a heavy tank. Consider this when setting up your aquarium. The next thing to consider is the type of fish tank.

The Different Types Of Fish Tanks

There are two main types of fish tanks. Glass fish tanks and acrylic fish tanks. When choosing the best fish tank, you have to consider which type you want. The type can influence things like weight. For example, glass is heavier than acrylic.

Each has its benefits and disadvantages. Glass aquariums are durable, scratch-resistant, and affordable. Acrylic aquariums are expensive but lighter than glass. They also won’t crack or break as easily as glass.

Glass Fish Tanks

  • Cost: Glass aquariums are cheaper than acrylic fish tanks.
  • Scratch Resistant: Despite being less durable than acrylic, glass fish tanks are more scratch-resistant.
  • Viewability: Glass fish tanks can affect your perception of things in the aquarium and distort the size of things in the aquarium.
  • Longevity: Glass tanks won’t yellow over time the way acrylic tanks do but it may have a green tint.
  • Support: Glass tanks don’t need as much brace support compared to an acrylic tank needs.

Acrylic Fish Tanks

  • Lightweight: Acrylic aquariums are 4-10 times lighter than glass aquariums.
  • Durability: Acrylic is a more durable material than glass. It reduces the risk of cracks and leaks.
  • Flexibility: Despite being super durable, you can still drill through an acrylic aquarium with ease if you want to set up an overflow system. You cannot do so with glass aquariums.
  • Repair: Repairing scratched or damaged acrylic is easier than repairing glass. Acrylic polishing kits are available at online fish stores like Amazon. Use these kits to remove scratches on the outside of the aquarium. Never use them on the inside.
  • Viewability: Minimal distortion of pets and plants in the tank. The location of the fish may be off, but it won’t distort their color or size. With glass tanks, there are a lot of distortions that obscure the actual size and color of your fish.
  • Clarity: High-quality acrylic aquariums are like housing your fish in an invisible container. That’s how clear the view is. It is more so evident in larger tanks when compared to glass aquarium types. For example, the more water needed, the thicker a glass tank needs to be. Solid glass can obscure your view. Thick glass can also add a green tint that distorts the color of items and fish inside the tank.
