Red-Eared Slider Tank Size: What’s the Best Option for Your Pet?

ByLinda Corley Updated

Red-eared slider tanks come in many different styles and sizes, but a plastic or glass enclosure is the best option for your pet. They allow the reptile to see outside and keep them safe from predators. It’s essential to choose the right size tank for your slider so they have plenty of room to move around but can still fit inside easily.

Quality of Tanks for Your Red-Eared Slider Turtle

GOOD: Glass Aquarium

A glass aquarium provides your red-eared slider turtle with all the ventilation and light they need. Plus, semi-enclosed tanks are just as good as glass aquariums in housing- they lack some of the aesthetic features of glass enclosures. So if you’re on a budget (or don’t have room for an elaborate tank), go with a semi-enclosed tank instead. Just be sure to buy one that’s big enough for your pet!

BETTER: Custom Turtle Tank

A custom turtle tank is the best option for those seeking an enclosure specifically tailored to their needs. It comes in various sizes and shapes, so you are sure to find the perfect one for your pet. There is no need to worry about ventilation – a custom turtle tank has this covered too! Plus, since you can choose everything from the substrate to the décor, it’s like building a mini aquarium just for your pet!

BEST: Indoor/Outdoor Pond

If you want to keep your turtle indoors, an indoor/outdoor enclosure is the best option, as they will have plenty of room to play and explore. But, on the other hand, a tank may be your best bet if you don’t have space or access to a pond. 

Remember that enclosures should be big enough for them to move around but not so large that they feel cramped – this is especially important if you live in an apartment! As far as enrichment goes, providing hideouts and toys is critical – otherwise, your slider will get bored quickly.

Tank Requirements for Your Red-Eared Slider Turtle

Fill the Tank With Water

Sliders are tank-loving creatures that need a lot of water to stay hydrated. You should fill the slider tank at least once daily and ensure that the slider’s water container doesn’t look dry. Notice any changes in behavior, such as reduced appetite, lethargy, decreased activity levels, or red scars on your body (especially around your eyes). It may be time to consult a vet. 

Shade and Ventilation

Sliders also need shade and ventilation – they can do just fine in an east- or south-facing windowsill. In addition to water, sliders need to eat a variety of food items. So, make sure to give them a balanced diet.

Creating a Basking Area

Red-eared slider turtles need a basking area to help regulate their body temperature. Without the heat, they can develop health problems, including bladder infections and scale build-up. If you have a turtle that isn’t using its basking area, provide one by putting a HeatBlock or heating pad on the bottom of its tank in wintertime. 

Many basking areas can be created in various ways, from using large tree limbs as nesting sites to setting up a climbing structure. Clearwater, wood chips and an artificial heat source are all great options. Make sure to provide basking areas for all your turtle’s needs – basking areas provide different temperatures, so be sure to experiment to find the perfect one for your turtle.

Maintaining Tank Heat

Maintaining the tank temperature for red-eared slider turtles is essential for their health and well-being. Ensure the tank’s water is at the correct temperature, close to 74 degrees Fahrenheit. If the water falls below this temperature range, it will need to be heated up before you can add new water. To do this, place the tank in direct sunlight or near a heat source like an oven or stovetop. If your tank’s temperature falls below this range, check the water levels and replace any evaporated water.

Installing an Ultraviolet Light

A turtle’s natural environment is their home, so ultraviolet light is an excellent addition to their captivity. This light helps regulate the turtle’s captive environment and stimulates their behavior, including eating and basking more often. 

To install an ultraviolet light, remove the old bulb and cover the exposed area with clear plastic or safety glass; then affix the new bulb using silicone adhesive or screws. Read your UV lamp’s owner’s manual for specific instructions on how to use it!

Tank Mates

Housing red-eared sliders in pairs or groups work best for their overall welfare and safety. If there are any problems between tank mates, it is best to separate them until they can be rehomed together correctly. If you’re looking to house red-eared sliders together and are unsure of the size requirements, remember that they can be of the same size and breed as long as they have the exact water needs. 

Remember These Tips When Acquiring a Red-Eared Slider Tank

Buy the Right Size of the Tank

Regarding red-eared slider tanks, size can be a significant factor. This is because the tank size can differ significantly between tanks, so it’s essential to be sure you’re buying the correct size before making a purchase. This will allow you to decide on the right tank for your home and aquarium.

Clean the Tank Regularly

Cleaning your red-eared slider tank is essential for keeping it odor-free and bacteria-free. Follow these simple steps to clean your tank every day: 

  • Remove all food and fecal material daily 
  • Wash the tank in warm water with a mild soap every other day 
  • Weekly use of an algae killer will help to maintain clear water
  • Let the tank air dry before replacing water and adding new fish

Preventing Problems During Tank Setup

Setting up your red-eared slider tank can be a lot of fun, but taking the necessary precautions to keep everything running smoothly is essential. 

  1. Always use a filter while setting up your tank, and be sure it’s the proper size for your aquarium. Larger filters will require more maintenance than smaller ones. 
  1. Next, set up your tanks in a calm area away from direct sunlight or drafts, and keep them covered when not in use to reduce heat exposure. It’s also essential to avoid introducing new fish to an established tank until you’re confident they won’t harm one another. 
  1. Make sure your aquarium has the proper water temperature before adding any fish.
