5 Best Breeder Boxes For Guppy Fish

Breeding guppy fish is straightforward. These colorful little fish breed fast. The hard part about breeding guppies is protecting the baby guppies. Adult guppies eat their young.

Thus, it is a good idea to separate adult guppy fish from the fry. When you separate the fry from the adults, you increase their chances of survival.

One right way to do this is to set up a breeding box for your guppies. A breeding box is a container that you attach to the main tank. It lets in water but keeps out adult fish. The guppy fry also cannot get out of the breeding box.

After the female gives birth in the breeding box, remove her so that she doesn’t eat her babies as well. Guppies do not lay eggs, so there will be tiny bite-sized baby guppies swimming around.

Here are some of the best breeding boxes for guppy fish that you can find online. They are an essential part of your guppy tank setup if you want to save guppy fry. All the breeder boxes below are affordable and practical choices. They work great for setting up a fish nursery.

Benefits of Using Breeding Boxes

Breeder boxes are cheaper to maintain. It works by using the resources of the main tank—for example, the heater and the filter.

These breeder boxes also match the current water parameters of the main tank—for instance, the TDS level, and pH level.

Breeder boxes are convenient because you don’t need to wait for a new aquarium to cycle. You can release the baby guppies in the main tank once they’re big enough.

One thing to note is that a breeder box is a temporary setup. You cannot keep guppy fry in one for too long. It slows down the growth of the baby guppies.

Only keep baby fish in the breeding box for two weeks. After two weeks, you can release the guppy fry into the main tank if there is enough space. Or, you can move the fry to a new tank.

If you don’t have space for a breeder box, you can use a separate tank or add some live plants to provide cover for baby fry. Live plants won’t save all the baby guppies, but it improves their chance of survival.

Separate tanks for baby fry should use the same equipment as the main tank. Also, keep the water conditions the same. Place the pregnant guppy into the separate aquarium before she gives birth.

Return her to the main tank after she gives birth. Try not to cause too much stress to the female during transfer as it might cause the guppy to die.
