Turtle Aquariums for sale We carry several different size turtle aquariums with turtle docks built into them. You must be very careful when purchasing turtle aquariums with built in docks as the gravel surface with most turtle tanks can do damage to your turtles shell, especially if they are baby turtles. Although our built in docks do have this gravel surface, we supply a much more turtle friendly attachment to place over the top of it. Height of the fixed dock is also very important as smaller turtles require less water and larger turtles need more. We have these kind of turtle aquariums in three sizes 60cm x 40cm x 44cm high 80cm x 48cm x 50cm high 122cm x 47cm x 60cm high The tanks are made from glass with an inner ledge that stretches from the front to the back of the tank, creating a study dry section the turtles can climb out onto(with soft surface dock). Each Turtle Tank comes with a large top-opening lid that locks securely in place. There are also spaces at the top for cords such as a cable for filters or water heaters to pass through with the lid still securely in place. Pressed circle areas in the mesh of the lid are easily pushed out to allow lighting to be fitted to the top also.
