How to Buy the Perfect Tank for Your Red-Eared Slider
There are a few factors that you should take into account when purchasing a new turtle tank for your red-eared slider, but it mainly comes down to its size and the type of tank that you choose.
The general rule when it comes to buying a turtle tank is to buy the biggest tank that you can afford, as your turtle will thrive in as many gallons of water as you can provide. If you can afford a bigger tank, don’t be tempted to buy a cheaper alternative as the bigger the tank, the happier they’ll be.
Furthermore, the more water that your turtle has to swim in, the less likely they are to drown. After all, we all want the best for our pets.
Check out the features below before purchasing a tank for your red-eared slider.
A big thing to take into consideration when purchasing a turtle tank for your red-eared slider is the size of their tank. Turtle tanks come in a variety of sizes: 50, 70, 100, 150, and 300 gallons.
If you can afford to go up in size, the larger the tank the better as a 50-gallon stock tank is generally not deep enough, at around 12 inches.
A red-eared slider tank should always be large as they need a lot of water to be comfortable in their habitat. Your red-eared slider tank needs to be filled with enough water so that your turtle will not drown.
This means that there needs to be enough water in the tank so that your red-eared slider can move freely and be able to rotate 360 degrees, while still being totally submerged in the water. It is also important to remember that your turtle will need a basking area as well as a swimming area.
So, depending on the size of your turtle, you’ll need a tank that is capable of holding more gallons of water than the minimum requirement that you measure according to their size.
Something important to consider when purchasing a tank for your red-eared slider is the maintenance it takes of it to keep it in a good condition.
It goes without saying that the larger the tank that you have, the longer it will take to clean, but it’s crucial that you do this for your turtle’s health and wellbeing.
Generally speaking, you’ll want to be cleaning your turtle’s tank once every week. You will need to replace some of the water in the tank with clean water when you clean out the tank too, even if your turtle’s swimming water looks clean, it could be high in ammonia or nitrite.
Every two to three weeks: you will need to clean out the whole tank and refresh the filter, too.
It is important that you clean and maintains your turtle’s tank as regularly as instructed to ensure that your turtle has the healthiest environment possible.
Something important to consider is how durable your turtle tank is going to be, as they can be an expensive investment depending on the tank that you go for.
Generally speaking, glass terrariums for land-dwelling reptiles tend to be thinner and are more likely to crack under the pressure from the water.
As a general rule of thumb, the tank glass should be between 6-10mm thick, although this is subject to change depending on the volume of water in the tank. For the most durable tank, you’ll want to invest in either a fish tank or ideally a specific turtle tank.
Rubber tank v Glass tank
The age-old question comes down to which type of tank is better, rubber or glass? Let’s break down some of the pros and cons of rubber tanks and glass tanks.
Generally speaking, as a premium aquarium, glass tanks are not only a lot more pleasing to look at, but you can also easily see what your turtle is doing.
Glass tanks are also much easier to set-up equipment in because most equipment is designed to use with glass tanks. They are available in a variety of sizes and shapes, meaning that you can provide your turtle with as many gallons of water as you can afford.
However, glass tanks are typically more expensive than rubber tanks and can be less durable because they’re easier to break. However, if the glass is thick enough to hold the water required, this problem is easily avoided as long as you’re careful when transporting your turtle tank.
Rubber tanks are good quality and are arguably more durable as they will not smash easily as a glass tank can. Rubber tanks are usually deep and wide, giving your turtles a lot of space to swim, and means they are less likely to grow out of their tank, meaning you won’t have to purchase another one.
They are easy to clean, maintain, and also drain water out of to ensure that you’re providing your turtle with the best environment possible. Much like glass tanks, rubber tanks also are available in a variety of sizes, from 50 gallons all the way up to 300.
However, rubber tanks are not nearly as aesthetically pleasing as sleek glass tanks. As they’re not transparent, they’re not a tank that you can display your turtle in and might end up looking like a bit of an eyesore.
It’s worth mentioning that you will need to do more work in terms of outfitting the tank with all the necessary gear your red-eared slider needs. This is mainly in reference to things such as a water heater, filter, UV lamp, basking area, etc. Most equipment is built with glass aquariums in mind, so you’ll need to adapt your rubber tank accordingly.
Something incredibly important to consider when purchasing your turtle tank is the lighting because your turtle’s life depends on having the correct lighting!
Like all reptiles, aquatic and semi-aquatic turtles need three kinds of light, all of which should be pointed at their basking area. They need a light that approximates normal sunlight, UVA (Ultraviolet A) light, and UVB (Ultraviolet B) light. You will need to replicate the light that they’d usually receive in the wild, in their tank.
Occasionally, you will find that some tanks come as a ready-to-set-up kit with certain lights, too. However, more often than not a tank will come just as a tank, and the rest will be an additional cost.
If you choose a tank that doesn’t have lights then it is your responsibility to install the appropriate lights and to ensure that your turtle’s environment is as natural to their wild habitat as possible.
Something else that is important to consider when purchasing a turtle tank is the features that it boasts, as the more features that it has, the more you’ll potentially be able to save on additional costs.
As you can imagine, there are a lot of aspects to think about when caring for a turtle. A lot of tanks come as a kit that makes your turtle’s environment easy and convenient to set up.
These kits are designed to make your life easier, that include essential features that make keeping and maintaining your turtle a lot easier.
From filters to water heaters, there are lots of extras that you require in a tank to take care of your turtle. As a result, you should consider which features the tank you’re looking at includes as it could end up saving you a lot of money down the road.

Frequently Asked Questions
What Size Tank Should You Have for A Red-Eared Slider?
We recommend that you get the biggest size you are able to afford and have the space for.
The reason is that generally speaking, it’s recommended to provide an aquatic turtle with 10 gallons for every inch of the shell (measured vertically).
One single red-eared slider will grow as they age and can get up to 10 to 12 inches, meaning 100 to 120 gallons!
Can You Keep Multiple Red-Eared Sliders in One Tank?
The shorter answer to this question is yes! You can keep multiple turtles in one tank, however, there are some things that you should consider such as their gender and the size of the tank that you’ll require to create a healthy habitat.
Namely, the more turtles that you have, the bigger size of the tank that you will require. You’ll need to get the biggest size tank you can get in order to reduce and minimize the risk of your turtles fighting.
The less space there is for your turtles to move around means that there is more opportunity for aggressive behaviors to arise. This is subject to change depending on their gender. Generally speaking, 2 males will fight each other the most, and 2 females will be aggressive towards each other the least.
The most common way to determine gender in a turtle is to look at the length of its tail. Typically, female turtles have short and skinny tails while males sport long, thick tails, with their vent (cloaca) positioned closer to the end of the tail in comparison to their female counterparts.
Another method of figuring out a red slider’s gender is to check their feet. If they have long, needle-like claws they are male. If they have shorter, more traditional-looking claws they are female.
