What Can I Fit in a 20 Gallon Fish Tank?
A 20 gallon fish tank is a great option for any aquarist looking to set up their first aquarium.
With the right setup, you can fit a lot of different types of fish in your 20 gallon tank.
Depending on the type and size of fish you’re interested in, you can easily house four or five small-sized species such as neon tetras or guppies along with two or three medium-sized ones like angelfish or discus.
If you want to keep larger species like cichlids, then one large variety should be enough to fill your tank – just make sure that there is plenty of space between them so they don’t fight.

Certain kinds require more swimming room than others, so if possible choose ones that won’t overcrowd your aquarium too much.

How Many Gallons Does a 20 Gallon Tank Hold?
A 20 gallon tank is an incredibly useful size for a variety of applications, ranging from fish tanks to water storage.
A 20 gallon tank holds exactly 20 gallons of liquid; no more and no less.
Depending on the material used for your tank it may hold slightly less or slightly more than this amount due to expansion and contraction in temperatures.
It’s important to keep track of your exact measurements when using a 20 gallon tank since if you overfill it you could risk spilling or overflowing, which can cause major damage if not handled properly.
Depending on the application you’re using it for there might be restrictions as far as how much weight the tank can safely handle so always make sure that any liquids put inside are within these boundaries.
What are the Inches in a 20 Gallon Tank?
A 20 gallon tank is a popular choice for home aquariums, and it’s important to know how many inches of space you need if you’re considering one.
20 gallon tank will measure approximately 30 inches long by 12 inches wide by 18 inches tall.
This makes the total volume of the tank equal to 360 cubic inches; however, this does not account for any decorations or accessories that might be added later.
As such, when planning out your aquarium setup make sure you have at least 4-6 extra inches in length and width than what is advertised as the size of the tank so that there is enough room for everything inside.
How Heavy is a 20 Gallon Fish Tank Full?
A 20 gallon fish tank filled with water will weigh approximately 180lbs. This is because a gallon of water weights 8.34 pounds, so when multiplied by the 20 gallons of water, you get 166.8 lbs for the weight of just the water in the tank.
However, it’s important to note that this does not account for any décor or substrate which can add additional weight to your tank and should be taken into account when deciding if your stand or table can safely support it.
If you are using a gravel substrate at 1 pound per gallon, then an additional 20lbs would need to be added on top of the original 166.8lbs before setting up your aquarium, bringing us to our total weight estimate of 186 lbs for a full 20-gallon fish tank.
Conclusion
The 20 gallon fish tank is a great size for many types of fish and can be easily incorporated into any home or office.
It provides enough space to keep multiple species together in one environment, making it an ideal choice for both beginners and pros alike.
With the right maintenance and care, your 20-gallon aquarium will provide you with hours of enjoyment!
