## Summary description

Katrinex frozen Daphnia in a 100 g pack provides aquatic crustacean feed suitable for many aquarium and pond fish species.

## Long description

Katrinex Frozen Daphnia in a 100 g pack is a frozen live-food alternative intended for aquarium and pond fish. Supplied frozen to lock in nutrients and simplify storage and portioning, these small aquatic crustaceans provide a natural source of protein and are suitable as a supplemental diet for many small to medium carnivorous and omnivorous species. The product is particularly useful for feeding fry, supporting natural foraging behaviour and varying routine diets without live-culture maintenance.
Advantages
Frozen Daphnia preserves proteins and essential nutrients through immediate freezing after preparation, offering a convenient, ready-to-use alternative to live cultures. The 100 g portion allows easy thawing and portion control while reducing the risk of introducing parasites or unwanted organisms compared with some live feeds. The texture and size of Daphnia make it attractive to many species and suitable for promoting natural feeding responses in aquarium and pond environments.
Suitable for
 Small to medium carnivorous and omnivorous aquarium fish
 Pond fish that accept frozen feed
 Fry and juvenile fish during rearing
 Supplementing flake, pellet or frozen diets to increase protein variety
Key specifications

How to use
Remove the required quantity from the freezer and thaw in a small amount of aquarium or pond water before feeding.

Use as a supplement to a balanced diet; do not rely exclusively on this product for complete nutrition unless advised otherwise for specific species or life stages.
Usage recommendations
Introduce frozen Daphnia gradually into the feeding routine and observe fish acceptance and water parameters.
