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

Very good food for small fish, fry, and I even feed it to my shrimp a couple of days per week.
