Frozen Daphnia Bio-Pure — 3.5 oz Cubes, Natural Laxative Food - Hikari

Hikari Bio-Pure frozen daphnia comes in 3.5 oz (100 g) cubes. These are small planktonic crustaceans, also known as water fleas, gut-loaded with bio-encapsulated multi-vitamins.

In this clip filmed at the store, we show how to turn an ordinary frozen food into something that feeds the fish and the rest of the tank.

The manufacturer's natural laxative

This is the claim Hikari leads with: daphnia can act as a 100% natural laxative for most freshwater fish, which in its words makes it an excellent choice for use after medicating.

This is the kind of product people look for when they have a problem, not when they are browsing. A fish coming off a treatment, a bloated fish that has stopped digesting: that is where daphnia earns its place.

Freshwater and marine — both

Unlike the worms in the range, Hikari intends daphnia for freshwater and marine environments alike. It names fry and other small-mouthed fish, egg-laying and livebearing species, invertebrates, and smaller marine fishes too.

How to feed it

Feed no more than your fish or filter feeders will completely consume within about a minute, up to four times per day. Remove whatever is left once the feeding period ends.

Hikari repeats it on every sheet: live or frozen food can spoil a fish to the point where it refuses its formulated diet. Feed it for variety, not as a replacement for complete nutrition.

What Hikari packs in

• A size almost any fish can readily consume and digest

• No-touch cubes that break away one at a time

Frequently asked questions

Why feed daphnia after medicating?

Because Hikari presents it as a 100% natural laxative for most freshwater fish, and recommends it explicitly for use after medicating. The manufacturer publishes no duration or precise protocol: its only numbered instruction is to feed up to four times a day whatever is consumed within a minute.

Is frozen daphnia suitable for a marine tank?

Yes. It is one of the few products in the range where the manufacturer names both: freshwater and marine environments, including invertebrates and smaller marine fishes.

How often should I feed daphnia?

Up to four times per day, giving only what the fish or filter feeders will completely consume within about a minute.

Shipping note: frozen food ships express in an insulated cooler with ice packs. Partial or complete thawing during transit is normal — especially in summer — and does not affect the product's quality for your fish. Dry ice would cost a fortune with zero quality benefit; we don't offer it. Be there to receive your package and place it directly in your freezer upon delivery.
