If you have fish that bully others or have fry that needs to be separated from adult fish, using an aquarium divider will save your from the expense of buying a second aquarium. Create your own homemade divider with items found at most retailers for very little time and money. This divider can be used repeatedly in tanks of the same size and allow for adequate water flow across the tank.
Things You'll Need
- Measuring tape
- Plastic embroidery canvas
- Binder bars
Measure the inside of your tank from the back wall to the front wall. Be sure to measure under the molding that is along the top of the tank for an accurate measurement. Measure again from the bottom of the tank to 1/2 inch under the top of the tank.
Measure a piece of plastic embroidery canvas to match your tank measurements. Mark your measurements lightly with a pencil at the top and bottom of the canvas.
Cut the canvas to fit your measurements carefully, keeping your lines as straight as possible. Uneven lines will lead to gaps in your divider, allowing fish to sneak through to the wrong side of the tank.
Cut binder bars to the exact length of both the width and the height of the plastic canvas. Slide them on to the edges of the canvas, ensuring that they are pushed in snugly.
Select an area in your tank to insert the divider. In the middle is the most logical choice unless you only have a few small fish in one side. Scoop the majority of the gravel in your selected area out of the way. Place the divider in to the gravel and wiggle it around until it is sitting on the bottom of the tank. Once it is in place, put the gravel back in to the hole to keep the divider in place.
