Live Daphnia Canada – Premium Live Daphnia for Betta Fish, Fry & Aquarium Fish

Give your fish the movement, nutrition and natural feeding response they were built for.

Our live daphnia cultures contain active freshwater daphnia (“water fleas”) used by breeders, aquarists and fish keepers across Canada for conditioning fish, feeding fry and improving natural feeding behavior.

Live daphnia are one of the most popular live fish foods because they provide movement, hydration and fiber-rich nutrition while encouraging instinctive hunting behavior in aquarium fish.

Unlike many dry foods, live daphnia stay active in the water column, helping stimulate picky eaters and supporting natural feeding responses.

Important Information

Daphnia are cultured in established freshwater systems. Because these are live aquatic cultures, harmless accompanying microfauna or microorganisms may occasionally be present. This is normal in natural live cultures.

Population density naturally fluctuates depending on reproduction cycles, culture age and shipping movement. Counts are approximate and cultures are sold by overall colony strength and density rather than exact individual numbers.

FAQ

Is live daphnia good for betta fish?

Yes. Live daphnia are widely used for betta fish because they encourage natural hunting behavior and provide fiber-rich live nutrition.

Can daphnia help constipated betta fish?

Many aquarists use daphnia as a natural food option because the exoskeleton provides roughage that may help support healthy digestion.

Can I culture daphnia at home?

Yes. Daphnia can reproduce quickly in properly maintained freshwater cultures with stable water conditions and light feeding.

What fish eat daphnia?

Daphnia are suitable for many freshwater fish including bettas, guppies, tetras, rasboras, nano fish, fry and juvenile fish.

Are daphnia counts exact?

No. Daphnia are live cultures and population density naturally fluctuates during reproduction and shipping.

How fast do live daphnia ship?

We use fast 1–2 day Canadian shipping whenever possible to help live cultures arrive healthy and active.

Should I feed all the daphnia at once?

No. Feed small portions at a time or culture them separately to create an ongoing live food source.
