S.K. Brine Shrimp Artemia Eggs - 50g 95% HATCH RATE (Pack of 2) Freshly hatched brine shrimp are the ideal first food for most newly hatched fish fry due to the fact that their movement attracts the fish. The critical time for fish fry is the first couple of days after hatching. Newly hatched brine shrimp if fed to the fry soon after hatching still have their egg sack attached & this is the finest fry food available.
