Make Your Own Aquarium Divider

It’s easy to make an opaque DIY aquarium divider water can flow through.

Tank dividers are essential for separating aggressive fish that might hurt each other (e.g., male bettas). They are also useful for isolating fish prior to breeding and for providing a safe haven for baby fish. In quarantine tanks, dividers also allow the quarantining of large and small fish in the same holding tank.

Starting with a clean sheet of paper, I designed an inexpensive tank divider meeting the following requirements:

• Opaque enough to reduce visibility
• Strong enough for most species, except large and boisterous fish
• Can be used with any type of aquarium cover
• Can be easily repositioned
• Allows sufficient water flow for filtration and heat distribution
