My guppies have become much more vibrant since switching to San Color Granules. The fish seem more active and their colors are noticeably brighter. No water clouding either, which is a big plus.

I’ve tried several color-enhancing foods, but this one stands out. The fish take the granules well and show better color development over time. Feeding is easy and the granules sink slowly, so they reach the middle water zone properly.

After a month of use, my angelfish have developed richer red and orange tones. The ingredients seem natural, and I don’t see any negative effects on water quality or fish behavior.
