Live Daphnia for Betta Fish, Fry & Freshwater Aquariums

Live Daphnia Culture – Premium Live Food for Bettas, Fry & Tropical Fish

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

Our live daphnia cultures are packed with active freshwater daphnia (“water fleas”) that are widely used by breeders, hobbyists and aquarists across Canada for conditioning fish, raising fry and improving feeding response naturally.

Unlike many processed foods, live daphnia trigger instinctive hunting behavior while also providing valuable fiber and hydration support. They are especially popular for bettas, nano fish, guppies, rasboras, shrimp tanks and fry grow-out systems.

Why Aquarists Love Daphnia:

• Excellent live food for bettas and tropical fish
• High-fiber exoskeleton supports digestion
• Great for conditioning breeding fish
• Ideal for fry and juvenile fish growth
• Encourages natural hunting behavior
• Lower in fat than many common frozen foods
• Can be cultured at home for ongoing production

Important Information

Daphnia are cultured in established freshwater systems. Because these are live natural cultures, there is always a possibility of harmless accompanying microfauna or microorganisms being present. This is normal in live aquatic cultures and does not affect the health or functionality of the daphnia colony.

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

FAQ for daphnia cultures

Is live daphnia good for betta fish?

Yes. Live daphnia are excellent for bettas because they trigger natural hunting behavior and provide fiber-rich nutrition that can support healthy digestion.

Can daphnia help with betta constipation?

Daphnia are commonly used by aquarists as a natural food option for constipated bettas because their exoskeleton provides roughage that may help support normal digestion.

Can I culture these daphnia at home?

Yes. Daphnia can reproduce quickly in a properly maintained freshwater culture with stable water, light feeding and no predators.

What fish can eat daphnia?

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

Are the daphnia counts exact?

No. Counts are approximate because daphnia are living cultures and population density can change during reproduction, packing and shipping.

Can other microfauna be present?

Yes. Because these are natural live cultures, there is always a possibility of harmless accompanying microfauna or microorganisms being present.

How fast do live daphnia ship?

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

Should I feed all the daphnia at once?

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