What Kind of Aquarium Do Red Eared Slider Turtles Need?

Red eared slider turtles (RES) are some of the most popular pet turtles in the world. Not only are they visually appealing, but they are easy to care for and can live up to 30 years with proper care. For any RES to thrive, it is important to understand what kind of aquarium they need.

Size of the Aquarium

When it comes to size, bigger is always better for RES. A 20-gallon aquarium is the minimum size, but ideally, an aquarium of 40 gallons or more should be used. This will provide enough space for the turtle to move around, swim, and bask.

When purchasing an aquarium, the setup should be taken into consideration. RES need an aquarium with a screen lid, as this type of lid will allow for proper air circulation and will prevent the turtles from escaping. The aquarium should also include a heater, a filter, and lighting.


The substrate of the aquarium is also important for RES. Sand or fine gravel can be used, but the substrate should be changed regularly to avoid the build-up of bacteria. It is also important to avoid substrates that are too large, as this could cause the turtle to swallow them, which can lead to serious health issues.

Decorations and Accessories

When it comes to decorations and accessories, RES need a mix of both. Rocks, driftwood, and live plants are all great additions, as they provide the turtle with something to hide in and explore. Just be sure to avoid sharp decorations, as these could harm the turtle.

Basking Area

RES need to be able to bask, so a basking area should be included in the aquarium. This can be done by setting up a platform that is big enough for the turtle to lay on. A basking light should also be used to provide the proper temperature for the turtle to bask. The temperature should be around 80-85 degrees Fahrenheit.

Water Temperature

The water temperature of the aquarium is also important for RES. The ideal temperature should be around 75-77 degrees Fahrenheit. A thermometer should be used to ensure that the temperature is kept consistent.

Water Quality

The water quality of the aquarium is also important. The water should be tested weekly to make sure that it is free of ammonia and nitrates. A filter should also be used to keep the water clean and to keep the water circulating.


RES are omnivores, so they need a varied diet. A combination of commercial turtle food, leafy greens, and live food such as crickets and worms should be offered. Feeding should be done in the water, as this will help to keep the water clean and also prevent the turtle from overeating.


The aquarium should be cleaned regularly to keep the water clean and to prevent bacteria from building up. The substrate should be changed at least once a month, and the water should be changed every two weeks.


RES should be checked regularly for any signs of illness. They should be taken to a veterinarian if any signs of illness are noticed. This will help to ensure that the turtle is healthy and happy.

Red eared slider turtles need an aquarium that is large enough to support the turtle’s adult size and swimming needs. A single red eared slider requires at least a 55-gallon aquarium with a minimum of 50 gallons of water, as they can reach sizes up to 15 inches. The aquarium should also include a basking area, a tight-fitting lid, and a filtration system to keep the water clean.

The aquarium should be large enough to provide the turtle with plenty of space to move around and explore. It is also important to provide ample basking area and areas of shade, as well as a variety of rocks, branches, and other decorations to provide the turtle with a stimulating environment.

What type of filter should be used for a red eared slider turtle tank?

The filter for a red eared slider turtle tank should be designed specifically for aquatic use. A good filter will provide mechanical filtration to remove solid waste from the water, as well as biological filtration to break down dissolved waste. Additionally, a good filter should provide plenty of water flow to maintain water quality and keep the turtle healthy.

When choosing a filter, it is important to select one that is appropriate for the size of the tank. A filter that is too small will not be able to keep up with the waste produced by the turtle, while a filter that is too large can create too much water flow, which can stress the turtle.

What kind of lighting is best for a red eared slider turtle tank?

The lighting in a red eared slider turtle tank should be designed to provide both heat and UVB lighting. The heat lamps should provide a basking area that is a few degrees warmer than the rest of the tank, while the UVB lamp should provide the turtle with the necessary UVB rays to synthesize vitamin D3.

It is important to provide enough lighting to keep the turtle’s environment warm and comfortable, while also providing enough UVB to promote healthy shell growth and vitamin D3 absorption. Additionally, the lighting should be on a timer to provide consistent light cycles.

What kind of food should be fed to a red eared slider turtle?

Red eared slider turtles should be fed a varied diet consisting of both plant and animal matter. The turtle’s diet should include dark leafy greens, such as kale and collard greens, as well as vegetables such as squash and carrots. Additionally, the diet should include animal-based proteins, such as live or frozen fish, shrimp, and worms.

It is important to provide a variety of foods in order to ensure that the turtle is receiving all of the necessary nutrients. Additionally, it is important to feed the turtle in a separate area away from the main tank to prevent the turtle from eating its own waste.
