I feed the exact same product to my "lowly" fish, or in a pinch for food. However, I do feed Wardley's Algae disks, as I noticed, like plecoperson did, their Spirulina content is higher than other brand I've seen, including Hikari (which I feed almost exclusively). But, my dwarf Gouramis, Tiger Barbs, and Serpaes all get fed that Flake. ^^
