Benjamin North –
My betta fish started eating more actively after I introduced the spirulina tabs. The tablets stick well to the glass and my fish can be seen feeding clearly. No fish seem stressed or avoidant. The spirulina content is noticeable in their color and energy level.

I use these tabs for my shrimp and snails. They sink nicely and don’t float. The fish enjoy them and seem to have better digestion. A simple, effective food option for herbivores.

The tablets are easy to apply and stay on the glass without falling. My cichlids eat them regularly and appear more active. No fish have shown any signs of illness or digestive issues.
