 How to care for baby guppies? Guppies are a great addition to your aquarium and are easy to breed. However, the mother fish will eat her babies if they remain in the same tank. Luckily, you can care for your baby guppies by placing them in a separate tank or providing hiding spots. Additionally, create an environment that supports their growth and feed them frequently. As they grow, check them daily to ensure they're healthy. Separating your baby guppies. Place the pregnant guppy in a breeder net or separate tank, if you can. Fit the breeder net in the corner of your tank. As another option, place the mother fish in a separate, small tank until she gives birth. This way your baby guppies are born in a safe environment. For example, you might keep your pregnant fish in a small 5 US gal 19L tank until she gives birth. After they're born, the baby guppies can live in this tank until they're big enough to join your aquarium. You can find a fish breeder net at your local pet store or online. They're fairly inexpensive, as you can find some for around $10. Don't put the breeder net near the tank filters pump, as the baby guppies might get sucked up into the filter.
