Instructions

    • 1

      Use a small fish net to herd the fish into a larger net. A coarse net is best for herding because it moves through the water faster. A fine net is less likely to snag a fin, making it better for capturing the fish.

      Remove plants from the aquarium to make it difficult for the fish to hide or avoid the net. Removing the plants is easiest if you grow them in containers or use plants that attach themselves to rocks or driftwood.

    • 3

      Lower the water level to stop the fish from swimming over or under the net.

      Place a divider in the tank to corral the fish at one end. A divider can be as simple as a piece of glass or plastic cut to the width of the tank.
