Make sure that you understand the needs of your fish species. This will help you set up your tank appropriately. For example, some fish prefer hard water to soft water, different species thrive at different temperature levels, and more.  Check out our archives of fish care articles to brush up on the needs of your breed.

What If the Baby Fish Caught You by Surprise?

You may not have an extra tank or the necessary equipment to set it up for baby fish. If you’re in a pinch, you can purchase dividers to separate adult fish from the fry. These may be referred to as breeders, breeding mesh, or box nets. These dividers are made of cloth mesh that isolates the fry from the adult fish but allows for adequate water flow, mitigating the need for a second tank. Breeders can also prevent the fry from the shock of being transferred to a new tank. They may thrive better in their own environment as long as they’re not able to become fish food.

How to Feed Baby Fish    

Baby fish care and feeding varies for different species. If the fish hatch as larvae, they will get their nutrients from an attached yolk sac. As the fry grow, the yolk sac will disappear, and you’ll need to feed them several times a day. Young fish prefer to eat live food during the first few weeks of life. Aquarium and fish stores should be able to provide you with appropriate food for your fish. Depending on your species of fish, you may need to feed them microworms, brine shrimp, or plankton. You can also purchase infusoria, a microscopic single-celled organism for the species that need them at most pet stores. It is important to suction out any visible food that the fry don’t eat to keep the tank clean.

Keeping Your Head Above Water

Pet fish care involves preparing for anything that can happen. If you’re not ready to raise baby fish, you might want to check with a local aquarium, fish breeder or pet shop to find out if they can take them. If you are ready to be the owner of several new fish, you may want to start a new aquarium with the babies. Some species of fish attack the smaller ones when you incorporate them back in the parent tank. Fish also need a good deal of space to grow into healthy adults. You may want to consider your space, time and equipment requirements before putting female and male fish of the same species together again and starting the process from scratch.
