    Golden Pearls is a revolutionary larval diet that has experienced great success in marine fish hatcheries in Europe. The secret to its success is an innovative manufacturing process which involves the agglomeration of micro-encapsulated particles that "traps" tiny air pockets inside of the feed particles. This results in a "non-sinking" particle diet that remains suspended in the larvae tank.

    The introduction of Golden Pearls has significantly reduced the dependence, and in some cases, replaced live feeds (rotifers and Artemia nauplii) in commercial marine fish and shrimp hatcheries.

    Golden Pearls are available in particle sizes from 5 to 800 microns. For comparison, a newly hatched brine shrimp is about 400 microns.

    Great as a larval fry diet and excellent for coral reef tanks! GP diets will remain in the water column longer and mimic planktonic animals by moving with the water current.

    Fresh product - great service!

    I have used GP for a long time, and with the new unexpected additions to the family I needed a fresh batch pronto. I bought 50u through 500u and am quite happy with the product and YFS service. Recommended!

    A high quality food for my cichlid fry

    My yellow lab fry get the 500-800 micron sized golden pearls and crushed cichlid flake

    Golden Pearls

    Excellent product for feeding fry & corals. Stays floating around all levels of the water column better than any product I know of, even Cyclop-eeze. Also great for small fish species (they love this stuff!!!) & filter-feeding shrimp & crabs.
