Live Daphnia (Water Flea) — Fresh Live Fish Food, Delivered Across the UK
Live Daphnia sells fresh live daphnia (water flea) shipped across the United Kingdom. Each 200ml pack contains roughly 100–200 live daphnia and costs £1.95, with a flat £4.95 UK shipping fee no matter how many packs you order. We dispatch on Monday, Tuesday and Wednesday only so bags never sit in a depot over the weekend — a welfare decision, not a logistics limit. Prefer a standing order? Our biweekly subscription ships the same pack every two weeks with 15% off each recurring order. We also stock tadpole bladder pond snails (Physella acuta) as packs of 15 for £7.95 — natural algae and detritus cleaners for aquariums.

Frequently Asked Questions
Where can I buy live daphnia in the UK with delivery?
Live Daphnia ships fresh live daphnia (water flea) across the United Kingdom from live-daphnia.com. Orders are packed and dispatched from the UK on Monday, Tuesday and Wednesday only, with a flat £4.95 shipping fee. We do not ship internationally.
How many daphnia are in a pack and what do they cost?
Each pack is a 200ml bag containing roughly 100–200 live daphnia. Counts vary per pack because we scoop from a live culture. A single pack is £1.95, and UK shipping is a flat £4.95 no matter how many packs you order.
Why do you only dispatch Monday to Wednesday?
Live daphnia are fragile in transit. Dispatching Monday to Wednesday means bags reach customers before the weekend, so they never sit in a delivery depot over Saturday or Sunday. This is a welfare decision, not a logistics limit.
How long do live daphnia survive in the bag, and how do I keep them alive longer?
Daphnia typically stay lively in the shipping bag for 24–48 hours after arrival. To keep them alive longer, open the bag on arrival, tip them into a wide container of dechlorinated aged water at room temperature, keep it well aerated but gently, feed sparingly with a drop of green water or yeast, and avoid direct sunlight.
Which fish are live daphnia best for?
Live daphnia are an excellent first food for fry and a natural staple for bettas, guppies, killifish, discus, apistogramma, and any fussy eater that ignores flake or pellets. The wriggling movement triggers a hunting response that dry food cannot.
Live daphnia vs frozen or flake — why feed live?
Live daphnia keep their full nutritional profile, encourage natural hunting behaviour, and act as a gentle laxative that helps prevent constipation and bloat in ornamental fish. Frozen and flake foods lose water-soluble vitamins and can foul the tank if uneaten; live daphnia keep swimming until they are eaten.
How does the biweekly subscription work?
The biweekly subscription ships the same pack every two weeks and applies a 15% discount on each recurring order. It is optional — you can also order a single pack whenever you like — and you can pause or cancel any time from your order confirmation.
