An Advanced Buying Guide to The Best Turtle Tank

​Tank Size

Turtles are playful, and they will swim, play hide and seek, bask in the light, and eat. As you can imagine, turtles need more space when compared to fish. Otherwise, they will feel cramped and become stressed.

A good strategy for figuring out your required tank size is multiplying the shell size by ten.

Sounds confusing?

Let me clear some things up.

If your turtle is 2 inches long, you should get a 20-gallon tank. Similarly, if the same baby turtle grows up to 10 inches in length, the optimum tank size is a 100-gallon tank.

A smart strategy is studying the species of turtle you want to buy beforehand. How big would it become once their reaches its full size?

In this way, you can plan ahead and get a large tank right at the start. You will not need to spend money twice. Remember, a bigger tank is always better for turtles.

Basking Space

Turtles often come out of the water and bask in the warmth and they love breathing fresh air. This is one of the identifying traits of the turtles.

This means that your turtle tank should have a docking space where they can bask. Remember, a basking space is of crucial importance for turtles. You can’t just have a tank full of water.

It’s good practice to keep the basking space in one corner or side of the tank. To achieve a better result, I suggest placing the light one foot above the basking area.

​Dual Temperature Setup

To create a perfect living space for turtles, you should also pay close attention to the temperature setup.

Being a cold-blooded animal, they don’t produce heat to keep their body warm. Therefore, it’s up to you to offer a different temperature to meet their needs.

I would suggest you follow a dual temperature setup. Divide the tank into two temperature zones – a warm zone and a cold zone.

​The basking space should have a higher temperature. The ideal temperature is around 90°F to 95°F. The other side of the tank should be colder. Here, the optimum temperature should range from 75°F to 85°F.

These temperature ranges are suitable for mimicking daytime. Once you turn off the lights and heaters, the overall temperature of the tank should range from 70°F to 75°F. This creates a nighttime environment.

​UV Light Availability

In the wild, turtles bask in the direct sunlight. As you have the tank in your home, you can’t provide them with sunlight.

To mimic natural sunlight, you should get a lighting setup with UV-A ad UV-B lights. Furthermore, the UV light should light the basking area directly.

Why do the turtles need UV lights?

​- UV-A keeps them happy, enhances their mood which helps them eat and breedUV-B strengthens their shells and bonesLight increases their overall body temperature

​More Powerful Filters

Turtles tend to make the water dirty quicker than fish. Therefore, you will need a more powerful filter or multiple numbers of moderately powerful filters.

The general rule of thumb is choosing a filter which is three times more powerful than a typical aquarium filter.

For example, if you have a 30-gallon turtle tank, go for a filter which is suitable for a 90-gallon tank or three filters suitable for a 30-gallon tank.

Your filter should also be capable of performing mechanical, chemical, and biological filtration. You can never compromise when it comes to filter choice.

For a turtle tank, canister filters are the best option as they are the most powerful option among all filters.

​Ease of Connecting Filters, Heaters and Other Components

One trait of a good tank is its functionality. As you have seen, you will need to install a lot of devices in order to create a comfortable living place for your turtles.

Therefore, a tank should be able to house all of these devices. I am talking about a filter, a heater, and other similar components.

​Proper Nutrition

Having a pet turtle means you need to offer them a balanced diet full of all the necessary nutrients. You need to create a balanced diet plan consisting of commercial pellets, live or frozen fish, and fresh vegetables.

How can you create a balance between all the foods?

Experts suggest offering 25% commercial pellets, 25% fish or proper insect, and 50% fresh fruits and vegetables.

If you have herbivore turtles, you can mix the diet with different types of mineral-rich fruits and vegetables.

​Tank Decoration

You must create a natural-looking environment for your turtles. You can decorate the tank with rocks, woods, moss, and other plants.

Try to design the two sides differently so that they can easily understand the differences between the warm and cold zones.

However, you must pick the plants for your turtle tank with great care. Turtles can be quite aggressive occasionally. They can uproot the plants from the substrate or damage the decorations quite easily.

Therefore, the plants or the greens should be able to tolerate heavy damages!

Durability Is Important

Turtles live a long life – they can live up to 40 to 50 years. Therefore, your tank should have the durability to house turtles for a long period of time.

This means that you can’t have a cheap tank for your turtles. Even if you are on a tight budget, you should take time and save up the money. Otherwise, you will have to buy a new setup after just a few years.

Rather than buying a new tank twice, it’s better to invest just once and buy a superior product. You should have all the necessary accessories ready.

Type of Turtles

Before making a rash decision, take some time to study turtles.

There are approximately 350 species of turtles in the world. Certainly, you can’t just keep any kind of species in your tank.

You can keep about 10 to 20 types of turtles in an aquarium.

The following table should help you choose a suitable turtle:

​You must understand that not all species of turtles live in an aquatic environment. Some are land turtles.

This is why some experts have divided turtles into two categories:

​- Land Turtles

​- Aquatic Turtles


​What is the Best Turtle Tank Size?

You should always buy a tank based on the size of your turtle. If you get a baby turtle, make sure you know the maximum size of the species of the turtle when it is fully grown.

For example, a baby African Aquatic Side-neck Turtle can be 1-2 inches in size, or even smaller.

However, upon reaching adulthood, they can measure up to 9 inches.

So, you should buy a tank which complements the 9-inch length of the adult African Aquatic Side-neck Turtle.

How do You Select the Right Size for Your Turtle?

As I mentioned earlier, according to the rule of 10x multiplier, the gallon count should be 10x time the inch count of the turtle.

Let’s follow the example from the previous section.

Assuming that you have an adult African Aquatic Side-neck Turtle, the optimum size of the tank for a 9-inch turtle would be 90-gallon.

​Where You Can Buy the Best Turtle Tank?

Always opt for buying a superior quality tank. Some species of turtles can outlive you, so you are creating a home for your turtle which will last for at least 20 to 30 years.

You can’t expect such longevity from a cheap tank.

I suggest you buy a tank from a reputable brand that you fully trust. You can buy a good quality tank from your local pet shop or dedicated aquarium shop.

My personal suggestion is that you buy the tank from online giants like Amazon.


They have the largest collection of tanks, so you can choose any tank of any size. Your local shop might not have a huge collection or a suitable tank dedicated to turtles.

What Does a Turtle Need in Its Tank?

Turtles need require a number of essential devices in their tanks. Here is a good checklist that you would want to have fof what you need to have in your turtle tank:

​Do Turtles Get Lonely?

No, they are not known for creating social bonds with others. In fact, they feel more comfortable living alone.

Even if you keep more than one turtle in a tank, they will stay away from each other and have plenty of individual space.

That being said, you should not handle your turtle too much, either. It might stress them out. Just leave them alone and let them enjoy their divine serenity!

What Is the Natural Habitat of a Turtle?

Turtles require both land and water. In the wild, they live near shallow coastal water with a large body of water nearby.

Naturally, they bask in the warmth of the sun to absorb heat then jump in the water when they feel it is necessary. As staying in the water for too long can damage their outer shell, they often come out of the water to dry off.

​Is Tap Water Safe for Turtles?

Generally, it’s okay to use tap water in a turtle tank. However, if you think that tap water is contaminated with too much pollutant, you should check the water quality.

If the water is too harsh for them, you can use a good water conditioner. This should make the water more habitable for the turtles.

​Do Turtles Need Rocks in Their Tank?

Not necessarily.

However, they need a raised dry platform which they can use to bask in the light. You can make a basking site with any kind of platform.

Whether you keep rocks in the tank or not is totally up to you.

Do Turtles Need Light at Night?

No, you will not need to give light at night to your turtles. As you are trying to mimic their natural environment, you must offer darkness just as you create light to mimic daylight.

​How Often Should I Clean My Turtle Tank?

​Turtles create a lot of waste compared to fish. Therefore, you must take extra steps to clean the turtle tank.

It’s a good practice to use a net to take large debris out of the tank every day. In addition, you should change 25% of the water every week.

You should also clean the tank every 15 days. However, the frequency may change depending on the quality of your aquarium filter.


​Today’s winner in the best turtle tank race is Tetra Aquarium Reptile Glass Kit. If you have a land turtle, then choose Zilla Reptile Starter Kit 10. These two are the best options you can find for your turtles.
