How to Use a Spawning Mop: A Guide to Breeding Fish in Your Aquarium
A spawning mop is used to collect fish eggs that have been laid by aquarium fish. To use a spawning mop, simply tie the mop to a weighted line and suspend it in the water near where the fish are likely to lay their eggs. After a few days, carefully collect the mop and gently rinse the eggs off into a separate container or incubator. Clean the spawning mop thoroughly before using it again.
