I personally use this when i first acquired my very picky CPDs and they all have full round bellies now. the 300-500 micron size works great for me. anything smaller is more powder like. ive handed out portions to people at swaps and all have said their fish love the stuff. If you are wanting to try it, 2oz costs $4. In terms of foods, it tends to be pricier but its worth it.

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.
