It’s hard to dive into the sea of aquarium options without knowing what you should look out for when choosing your first fish tank.
Below are some criteria to consider when looking for the best fish tanks.
Deciding on the aquarium size depends on the kind and number of fish you want to take care of.
If you plan to keep a large fish species or several small fish, choose a bigger fish tank.
The typical aquarium size for beginners should have at least 10 gallons of water capacity.
Contrary to what you might think, larger fish tanks are easier to clean and maintain.
The fish tank material is another factor you need to take into consideration when buying an aquarium.
At the moment, there are two popular material types for fish tanks: acrylic and glass.
Hence, the continuing discussion on which one is the best option.
Acrylic fish tanks tend to be brighter, more lightweight, and more durable than glass aquariums.
They are also energy efficient, providing better temperature insulation.
The problem is, acrylic fish tanks are more susceptible to leaks than glass aquariums.
On the other hand, fish tanks made from glass material are more durable and do not scratch easily or turn yellow.
3. Saltwater or Freshwater Tank
After choosing the size and material of your fish tank, it’s time to decide between saltwater and freshwater aquarium.
When deciding between the two ecosystems, you need to consider several factors, like cost and maintenance.
The standard freshwater tropical fish tanks are the ideal choice for first-time aquarists.
However, additional expenses and maintenance are required if your aquarium is full of plants.
Freshwater species are enduring and more affordable but not as colorful as saltwater creatures.
Alternatively, saltwater fish tanks are more expensive and trickier to maintain because they require additional equipment and special lighting.
4. Tank Placement
Tank placement is another critical factor to consider.
Knowing where you plan to install your aquarium helps you decide on its size.
It will help if you place it where people can see it without trouble, as it may stress out the fish.
Keep it away from direct sunlight to prevent algae formation and temperature fluctuations.
Air drafts can also upset your fish tank’s environment. For this reason, you should not place it near vents and windows.
If you don’t have any issues with your aquarium’s setup, then that’s well and good.
Otherwise, this will also affect your choice.
For those on a tight budget, choose the one within your means and upgrade later on.
