Why Do I Need a Tank Divider?

Tank dividers aren’t just good for separating turtles. They are a great way to protect adult turtles from spawn. This can help with dividing different species of turtles. Additionally, you can use tank dividers to protect weaker fish. If you’re trying to create a tank where turtles and fish exist, using dodgers is your best option. 


What Are the Benefits of a Tank Divider?

  • Tank divider frees you from having to create a separate tank. 
  • Tank dividers allow water to pass through, so you don’t have to buy an extra filtration system. 
  • Tank dividers are used to help separate aggressive turtles


What is the Disadvantage of a Tank Divider? 

  • Inconsistent water flow – Water quality in one area will be better than in the other.
  • Varying Water Temperature: The water temperature will change from different sides of the tank. Areas that are in closer proximity to the heater will receive more heat than others. 
  • Aesthetic Value: Tank dividers will break up the tank and might dilute the aesthetic value of the tank. 
  • Preventing Predatory Behavior: Some tank dividers are not durable enough to stop all aggressive behavior, especially if the turtle can see through the divider. 

What Else Should I Know About Tank Dividers? 

To create an effective barrier, you have to install the tank divider properly. Ensure that the sides of the divider are placed against the tank walls. Bury the bottom of the dividers so your turtles cannot swim against them. 

Another thing to consider is the proximity of the filter and heater. While water will flow from one area to the tank to the other, the further away side receives less filtration. To solve this, move the filter closer to the center of the tank or add an additional filtration on the other side of the tank. Since water flows from one side of the divider to the other, tank dividers can be difficult for injured turtles. The only way to reduce disease is by removing the sick turtle from the main tank and placing them in a quarantine tank.
