Best Aquarium Size
An underwater habitat contained in a glass cube, the larger the space, the better the habitat will be able to sustain itself. With that said, a bigger fish tank is better. Of course we are not all free to set up our own home Georgia Aquarium, budget, space and time limitations always prevail!
Before you buy an aquarium, go to the pet store & browse the freshwater fish department to determine what blend of aquatic creatures you’d like to keep. This will be a starting point for determining size.
Guidelines on choosing an aquarium size:
For a collection of small schooling fish, 10 to 30 gallons is suitable however 10 gallons cannot hold many fish, I suggest choosing this only if available space is a main limitation.
For a family hobby, my personal preferred size is around 29 gallons. It’s big enough to hold many fish giving the kids something to exciting look at and the maintenance requirements are not too cumbersome.
For an adventurous family hobby, 55 gallons will offer excellent opportunities to have all sorts of creatures like amphibians, fish schools, large individuals, eels and catfish. The length of the 55 gallon helps everyone claim a territory for better peaceful living.
Consider the maximum size of the species. Keeping larger tropical fish species like piranhas, some sharks, tin foil barbs or big cichlids will need at least 40 gallons.
Fancy goldfish require minimum 30 gallons as they get quite large and messy creating a heavy bio-load. Growth can be stunted of not given enough space. Even though they are slow movers, they need plenty of room.
For 70 gallons and up, consider the floor structure – water weighs 3.78 pounds per gallon plus the weight of the aquarium. The most popular large size is 90 gallons, but consider that a 90 gallon aquarium filled with water can weigh 1000 pounds. With that said, a big aquarium is best placed in a basement.
Aquarium shape is another important consideration. A tall tank will be more difficult to reach the bottom although it may look nicer from the larger viewing area. Bow front aquariums are a stylish addition and look elegant along with fancy furniture in a formal living room.
We strongly advise avoiding fish bowls. They don’t offer enough space and lack of aeration usually causes smelly water problems and premature death. The only exception is Betta fish which should always be in a bowl-type container.
Purchasing a pre packaged starter kit from a pet store in your budget range is an excellent way to get started, you’ll need to add decorations and fish, but the most important accessories and equipment are already included.
