Live Food Options for Guppies

live fish foodGuppies thrive with a varied diet that includes live food. This is especially true for sick, pregnant, and young guppies. Some types of live food you can hatch or “seed” yourself while others can be purchased at fish supply store. Here are some options for feeding your guppies.

Microworms are just large enough to be visible with the naked eye and they’re a good option for feeding guppy fry. Microworms, which come from Sweden, grow in many types of media. You can start a colony of microworms on a bread and yeast solution that’s kept almost liquid. Keep the colony covered in a glass jar with smooth sides as they will start to crawl up the edges of the container when the colony becomes dense. To feed your guppy, scoop some out with a butter knife and dip the blade into the water.

Your fry will probably need to be trained to eat microworms although, once they do, they will quickly become a favorite food.

Baby Brine Shrimp
Adult guppies and fry love baby brine shrimp. You can buy the small brown eggs at a tropical fish store, but it’s usually easier to buy them in a can and then hatch them at home. While your guppies will gladly consume a great deal of baby brine shrimp, don’t go overboard. Baby brine shrimp are very high in fiber but they don’t have much else to offer in terms of nutrients: feed your fry too much brine shrimp and they will likely be stunted.

A good strategy is giving your fry flake food as their first meal of the day to give them a good mix of nutrients. You can add a serving of baby brine shrimp later in the day.

Mosquito Larvae
The dark larvae that develop from mosquito eggs are a true delicacy for grown guppies. If you want to feed mosquito larvae to your fry, the best way to do it is collecting the small egg-filled rafts that mosquitos leave behind. Let the raft float in the tank and the fry will eat the larvae right as they hatch and move into the water.

Harvesting mosquito larvae yourself to feed to your guppies is a bit tricky. Make sure you don’t bring home more than your guppies will eat in a day. Otherwise, the larvae will become mosquitos flying around your home. You can also get frozen mosquito larvae if you don’t want to find them yourself. Most people find it more convenient to use freeze-dried blood worms.

If you don’t mind catching earthworms in your yard, guppies love shredded earthworms. You can keep the earthworms unfed for a day or so before shredding or rinse the shredded earthworms before adding them to the tank, otherwise they will make the water murky. The easiest way to catch earthworms is pouring a solution of potassium permangenate onto the grass. After a few minutes, you will see earthworms start to emerge.

While some guppy breeders choose to feed their guppies daphnia, live daphnia are very expensive and they have a short lifespan, which means you need to feed your fish as soon as you return home. Daphnia also need to be kept cold and inactive. If you want to feed your guppies daphnia, try raising them yourself with a starter kit.

Tubificid Worms
Tubificid worms are a common type of guppy food sold in most fish supply stores. There are many species of tubificid worms, some of which live in water below sewers. Be careful feeding tubificid worms to your guppies as they can carry all types of bacteria and diseases that can infect your fish.
