Yes. They are. The 30-gallon fish tank is a mid-sized tank, perfect as a nano tank. It is not much large or too small, making it ideal for beginners who would love to keep more than one fish.
A 30-gallon fish tank is actually not on the standard aquarium size list like the 30-gallon breeder tank, but you can buy this size from your local aquarium shop without any problem.
As a experienced fish keeper if you are looking for a versatile fish tank that can be used as a freshwater aquarium or a saltwater aquarium, then this would be the size you should consider.
Its size fits almost any corner, including your living room, office, and school, and it still can hold a considerable amount of fish without any problem.
How heavy is a 30-gallon fish tank?
30-gallon fish tanks are typically made of glass, and since it’s not much larger than a standard 29-gallon aquarium, it usually weighs around 40- 50lbs.
30-gallon glass tank is light enough to be carried by one person, but you should always have help setting it up or moving it once set up.
When the tank is fully stocked, it will weigh around 350 pounds (159 kg). So, once your tank is set up, it is not easy to move around.
However, if you buy a tank made of acrylic instead of glass, it might be a lot lighter since acrylic is much lighter than glass.
30-gallon fish tank dimensions
Since the length of 30-gallon fish tanks varies depending on the manufacturer, it’s hard to say what would be its exact height and width.
However, most 30-gallon tanks are between 13 and 20 inches wide, which makes them perfect for almost any room.
The standard size for a 30-gallon fish tank would be 36″x13″x16″. However, the measurements change in the 30-gallon breeder tank.
A breeder tank should have a more square-like bottom and a low profile for the breeders to access fish fry easily. Therefore the breeder tanks are made with lower heights with more widths.
A 30-gallon breeder tank would usually measure 36″x18″x12″. But, this tank is not ideal as a display tank because of its low height.
30-gallon fish tank in liters
A 30-gallon fish tank can hold, well, 30 gallons of water. In liters, it can hold about 113 liters.
However, you should add less than the actual water amount because the substrates, decorations, and equipment like filtration and air pump will take up some space.
30 gallons (113 liters) should be the maximum amount of water you can keep in a 30-gallon tank.
How many fish can I put in a 30-gallon tank?
The number of fish you should put in a 30-gallon fish tank is determined by your aquarium’s size and the species you keep.
It’s usually better to keep one inch of fish per gallon of water. However, it’s always better to keep less fish than more since you will need a lot of filtration and good maintenance if you keep more than one fish.
So, as per the calculation, you can keep about five freshwater species such as goldfishes that are about 6 inches long each. (5*6=30).
On another note, this condition applies to marine species in saltwater environments in the same manner.
However, this is a rough estimate, and you should consider the activity level as well as your fish’s temperament level before stocking up your 30-gallon aquarium.
Further, if you choose to fill up your tank with plants and decorations, the space your fish gets to swim around lessens dramatically. So, you should think through that factor as well.

How much would a 30-gallon tank cost?
The price of a 30-gallon tank varies depending on the
- shape and design and
- included equipment.
There are mainly two materials from which a 30-gallon tank can be made – glass and acrylic. Both materials have their pros and cons.
Acrylic tanks are lighter in weight, but on the other hand, they are more expensive than glass ones.
An acrylic tank can also be easily scratched and may develop cracks after a few years of use, which makes it useless.
Glass tanks, on the other hand, are very durable, but they are heavy and not the best option if you want to replace your tank often.
A simple rectangular shaped 30-gallon glass fish tank would cost you around $300 to $500. On the other hand, a 30-gallon acrylic tank will cost you more than $600 per piece.
The shape of a 30-gallon tank also determines its price. Rectangular or hexagonal tanks are the cheapest, while round and bow-fronted ones are the most expensive tank in this category.
Finally, the design of the tank also affects its price. A basic 30-gallon tank is cheaper than a high-tech one that comes with advanced filtration systems.
The 30-gallon tanks are not very expensive to buy, but you will have to spend more money on the filtration system and equipment.
Some tanks come with a basic equipment kit that will help you in getting started. The kit includes lighting, a filter, a pump, and a heater.
This kit will cost you an extra $50 to $100 but, it is worth buying if you are new to this hobby.
Finally, if your budget is tight, you can always consider buying a second-hand one. A used 30-gallon tank would cost you around $200 or less.
The condition of the tank also matters so you should check it thoroughly before buying.
What to consider when buying a 30-gallon tank?
When setting up an aquarium, you can not just buy a tank and place it wherever you like. There are some things to consider before buying your fish tank.
The positioning and placement of your aquarium will determine the health of your fish. There are many things to consider for this, such as:
- The amount of direct sunlight your fish tank gets
- The air condition in your room
- Your noise levels and risk of an earthquake
- The temperature of your room
- Whether or not your walls are insulated etc.
Mainly the place you choose should be a calm, cool place that doesn’t get direct sunlight as sunlight causes heavy algal growth.
Fish tank shape
Once you have decided on a place for your aquarium, the next thing you should consider is the shape of your tank.
The most common shapes are rectangle, hexagon, or bow front. A rectangle is the cheapest one but if you want to create an active environment for your fishes, then go for bow front or hexagonal aquarium.
If you are planning to buy a 30-gallon tank, you definitely need to consider the size of your fish.
If you are not sure about how large or how small your fish will grow, you should be prepared to change the size of your tank in the future.
You can avoid this by buying one that is slightly bigger than you need. However, keep in mind that a tank that is too big will make maintaining it difficult.
The other important things to consider when buying a tank are the filtration system, heater, and lighting.
When purchasing an aquarium, you should never forget that the tank size, filtration system, heater, and lighting are different components of the same whole.
Lighting is more important than you think. The lighting must be adequate so that algae will not grow excessively in the aquarium.
You should also buy a filtration system that is easy to maintain. Too complicated filters are difficult to operate, so you should always go for simple ones.
Don’t forget about the heater. Buy a good quality heater that can maintain the temperature of your tank without any fluctuations.
Nothing will work as you expect if you have a low budget for an aquarium.
Not only the cost of the fish tank, equipment, and fish, you should also consider the monthly cost of running the aquarium.
You will have to spend on electricity, water and cleaning supplies, water testing kits, food, and medications monthly basis, and it will make your budget go over if you are not ready for it.

Before adding your fish, you MUST cycle the tank for at least two weeks to build up beneficial bacteria. After cycling the tank, check for water parameters with a water testing kit.
The Ammonia, Nitrite, and Nitrate readings should be 0ppm to add your fish. If the readings are fine, you can introduce your fish to your new aquarium.
