My angelfish have been eating this flake consistently for three months. Their color has become much brighter, and they seem more active. The flakes are easy to distribute and the fish show no signs of digestive issues.

I switched from a standard flake to this Spirulina version and noticed a noticeable improvement in my betta’s fin condition. The fish are more vibrant and seem healthier overall. A bit more expensive, but worth it.

The fish in my community tank are now more active and their color has deepened. The flake is well-balanced and the fish don’t seem to waste much food. Great for algae-eating species.
