5 Gallon vs 10 Gallon Fish Tank- Detailed Discussion

Comparison of 5 vs. 10 Gallon Fish Tanks

1. Space

First of all, you have to consider the space that you are about to put your fish tank in. This is because aquariums are a delicate thing and you don’t want to put it in a place that is unsafe and already congested.

2. Budget

If you are tight on budget then probably it’s best for you to get a 5 gallon fish tank. 

Aqueon LED MiniBow Small Aquarium Fish Tank Kit can be a wonderful option for you when you are looking for a good aquarium on a low budget. Because 

Aqueon is a world-famous brand in the aquariums section that offers its products in various price ranges.

  • It’s a rectangular fish tank made of high-quality glass along with clean silicone sealed edges.

3. Maintenance

The basic maintenance work is that you have to feed the fish, test the water condition and monitor it regularly. Also, you will need to change water more frequently.

Larger tanks need more time and work to maintain the activities. Otherwise, the health of the whole system along with the fish will be in danger.

This is why, if you are a beginner I would recommend you to try the smaller aquarium at first so that you can get the hang of all the maintenance work it needs before getting a larger one.

I started my aquarium journey with a 5 gallon tank because back then I was very busy and I didn’t have much extra time in hand to do frequent cleaning of the aquarium as well.

What Kinds of Fish Will Suit My Aquarium?

Fish selection for aquarium

The most important thing here is, what type of fish you want to keep in your tank will have a huge impact on the choice of tank size. Normally, It’s not a good idea to keep a number of big fish in small tanks.

Because this will restrict their movement and the fish won’t be happy there. Besides, the larger fish will make the water more dirty very fast. As a result, the tank condition will not certainly be ideal.

However, if you plan what’s the best fish species according to the size of your aquarium things will become easier for you.

For 5 Gallon Tanks

When you are willing to get a 5 gallon fish tank, naturally the choice of fish species becomes limited because of the tank size. 

If you are wondering about what fish to buy, I’d say you have plenty of options. When I had my 5 gallon fish tank I tried keeping many kinds of fish including, guppies, mollies, betta fish, harlequin rasbora, neon tetras, cherry shrimps, etc.

However, do remember to keep the fish number around 4-6. And in case you are getting yourself betta fish make sure to choose the tank with a lid because they can occasionally jump out of water.

For 10 Gallon Tanks

If you are getting a 10 gallon fish tank then you can put around 10 fish at maximum. However if your fish species grows larger over time, limit the fish number to around a maximum of 8. This will help you to keep the tank healthier and cleaner.

Luckily, there are many species to choose from when you are getting a 10 gallon fish tank. You can get yourself guppies, betta fish, neon tetras, zebra danios, mollies, cardinal tetras, dwarf gourami, goldfish,  golden dwarf gourami, etc. 

Besides, you can do a lot with a 10 gallon tank such as adding different aquatic plants, rocks, and other decorative materials due to the extra space in the tank.

Frequently Asked Questions (FAQs)

What Shape Of The Fish Tank Is Best?

Round, square, and rectangular, aquariums are available in all shapes. But most aquarists prefer the rectangular shaped aquarium because it has a wider water surface compared to the water volume than any other shapes. And this allows more gas exchange in the water.

How Often Do You Change The Water In A 5 Gallon Fish Tank?

As a thumb rule, 25 % of the aquarium water needs to be changed every two to four weeks. However, you can definitely just change the water without removing the fish from the tank. Make sure to keep the tank clean otherwise, your fish health will deteriorate.

As a beginner, one should start their aquarium keeping hobby with cherry barbs, guppies, neon tetras, white cloud minnows, etc. Because these fish are friendly and very less demanding and also they do well in almost any condition.

While it is technically possible to keep fish in a 5-gallon tank, it is generally considered a small volume for fish to thrive in. The small size restricts the swimming space and can lead to poor water quality if not properly maintained Low-maintenance fish like bettas or a few small schooling fish (such as neon tetras or guppies) can be suitable for a 5-gallon tank.

Can I Put 10 Fish In A 5 Gallon Tank?

It’s not a good idea to put 10 fish in a 5-gallon tank. The general rule of thumb for stocking a fish tank is to have one inch of fish per gallon of water. In a 5-gallon tank, you can comfortably accommodate around 2-4 small fish, as long as each fish doesn’t grow larger than 1 inch.

A 5-gallon tank wouldn’t be the right choice for a goldfish. Goldfish require ample space to swim and explore their environment. In a smaller tank, the water quality can deteriorate quickly and lead to health issues for the goldfish. To ensure the happiness and health of your goldfish, it is highly recommended to provide them with a larger tank, ideally ranging from 10 to 20 gallons or even more
