Most fish keepers are always anxious to see the new life that will be born in their aquariums or ponds. But things can be difficult if a spawning season is proving to be difficult because you have been trying hard to get your fishes to spawn, but they just weren’t cooperating.

You must have tried all kinds of tricks, but nothing seemed to work. Some fish keepers even go as far as buying a special heater that was supposed to help stimulate spawning, but it didn’t make a difference. The fishes just wouldn’t do it.

You don’t have to feel discouraged because it’s totally understandable that you have been working so hard to get things to work and it just wasn’t going well. But the question is have you tried simulating your fish’s natural habitat? Have you tried to re-adapt their surrounding to look like their natural habitat in the wild does when it’s time for spawning?

Well, that could be the solution you are looking for and spawning mops could help you do the trick and encourage your fish to start spawning.

What is a Spawning Mop?

A Spawning Mop also known as Breeding Mop is basically a bundle of green yarn, wool, or string that has been tied together to form a big mop head like strings or yarn to help encourage fish spawning so female fish can lay their eggs. It can be made from different materials like nylon, acrylic, cotton, and even wool. A spawning mop can be easily created at home, and can also be bought from most pet stores.

As you can see, Spawning Mops are very easy to make and can be made from different materials. You can even buy them from most pet stores.

How Does a Spawning Mop Work?

When female fish are ready to lay their eggs, they will often look for places where there are lot of vegetation and plants to help them hide their eggs. The female fish will lay her eggs in amongst the plants and then the male fish will come along and fertilize them. The fry will then hatch and have plenty of places to hide in the plant vegetation from predators as they grow big enough to fend for themselves.

The problem is that most aquariums or ponds don’t have the right kind of plants that are required for spawning. This is where a Spawning Mop comes in to help encourage fish spawning.

Spawning Mops works by simulating the look and feel of plants that are found in a fish’s natural habitat. But instead of using plants, they use materials like yarn, wool, and cotton cord which is usually green to stimulate a plant environment lookalike.

The spawning mop is then left in the aquarium or pond so that the material of the mop will catch the eggs as they are released, and it will also help to keep them safe until they hatch.

Eventually, the material of the mop will start to disintegrate and fall apart which is totally fine because as it does, it will release bits of material into the water which will help to encourage your fish to start spawning because it simulates their natural spawning environment.

It’s recommended to leave the spawning mop there in the pond or aquarium until the spawn has been completed. After the spawn is complete, the mop can then be removed and the fry can be left to fend for themselves.
