The Best Fish Tank Sizes For Every Occasion
Fish Tank Size
What are the best fish tank sizes for your home, your office, or your child's first pet fish? The fact it, there is an appropriate size of aquarium for every occasion. What you need to do is figure out what you intend to use the aquarium for, how many fish you want, and how much effort you want to put forward. Once you do that, the choice will become clear.
For example, if you want a lot of fish you will want a 20 gallon tank or larger. If you want to create a coral reef even bigger is better. Are you just looking for a nice home for a betta fish? If so, a nice 2 gallon might be perfect.
To make it real simple, here are the recommended fish tank sizes for every occasion.
Single Fish Tank
To create a nice home for a single fish like a colorful betta fish or goldfish, a 2 gallon tank is plenty of water to create a suitable environment that will keep your pet healthy for a long time.
Small fish tanks like a 2 gallon tank are very attractive and come in many shapes, none more popular than the classic hexagon or octagon tanks that offer viewing from all sides. The nice thing about these little tanks is that they are easy to care for and clean and they take a minimum of space, so you can fit an aquarium on a desk, a night stand, or even a counter top.
The other nice thing is that, unlike a plain fish bowl, a 2 gallon aquarium will allow you to use a filter to keep the water clean. That is a good thing that you won't regret.
Beginner Tank for Multiple Fish
For the aquarium beginner that wants to dabble with a new aquarium but avoid having a huge tank that requires extra care or a more significant aquarium stand, a 10 gallon tank is the perfect place to start.
A classic 10 gallon tank will sit nearly anywhere and doesn't weight so much that a table can't hold it. A general rule for holding fish is that an aquarium will hold about 1 inch of fish per gallon, so a 10 gallon fish tank could support up to 10 small tropical fish, though 8-9 would be even better.
A 10 gallon aquarium is small enough to easily reach all corners and supports a nice variety of fish, but it won't break the budget, as you will find full 10 gallon systems with everything you need for an affordable price.
If you feel confident that you will stick with this aquarium, a 20 gallon tank is a nice upgrade and is still small enough that you can find a spot for it in nearly any room.
Fish Tanks for Saltwater Fish
Saltwater fish are a blast to raise and care for but to really get the most out of them you want to be able to get saltwater aquarium fish that will grow up to be nice specimens, like 3-4 inches long in some cases or even more. Because of this fish size you will want at least a 20 gallon tank.
A 20 gallon tank will only hold a small number of attractive saltwater fish, so if you want more, consider going with one of the big boys - 40 gallons or more. You really can go much larger if you have the space for it, but an aquarium stand is a must for this much weight. With the water, a tank of this size will weigh hundreds of pounds, so support it well.
When choosing a tank for saltwater fish, select a vertical tank - one that is taller than it is deep. This will allow you to add tall coral and really make a statement.
Safety Tips for Aquariums
Before you make your move and set up your new aquarium, adhere to these important safety tips for placing aquariums.
First, don't put an aquarium right in front of an outlet. There is water in that tank and you need to be aware that water and electricity don't mix. Also, make sure there is a drip loop in your cord. That means that the cord goes below the outlet and then back up before it is plugged in. This insures that any water dripping down the cord cannot make it into the outlet.
For support, know that a gallon of water is heavy, and 10 or 20 gallons is really heavy. Use a properly supportive table or aquarium stand to make sure it is supported and won't tip over.
Choose Your Fish Tank
It's time to choose your tank. For a single fish, go with a 2 gallon with a filter. To get your feet wet but avoid going all in or for a small space, check out the 10 gallon tank. If you are committed or going for a saltwater tank, start at 20 gallons and go up from there. These are the best fish tank sizes for any occasion.
