Guppy Fry: Care and Feeding
Veterinary & Aquatic Services Department, Drs. Foster & Smith


I have a beautiful pair of Red Cobra Tux guppies, and it appears that the female is pregnant. What's the best way to separate the fry from the other fish and what should I feed them?


Ideally, a separate aquarium should be used with simple filtration, such as a foam filter with a heater for temperature control. The pregnant female should be placed in the breeding tank just before she releases the fry. After all of the fry have been released, it's important to remove the female and return her to the main display aquarium. If it's not possible to set up a separate aquarium, there are several drop-in breeders available. These units include; Fresh Flow Breeding Unit, Aqua-Nursery, Two-Way, Three-Way, Five-Way Breeder, as well as the Fish Net Breeder. Some of these units require an air pump, and they all include easy to follow instructions.

From the first day, the fry should be fed a quality food, such as baby brine shrimp. Baby brine shrimp are available frozen, or you can hatch your own with hatcheries such as the Brine Shrimp Hatchery Kit or the Aqua Breed 200 or 1000. There are also liquid and dried foods available specifically for fry, such as; Liquidfry No. 2, Artificial Artemia, and Artificial Rotifera. At this stage in development, it's best to feed the fry small amounts several times a day.
