My betta fish has started eating the spirulina tabs regularly. The fish seems more active and the color has improved. The tablets stick well to the tank wall and I can see my fish eating without needing to move them.

Great product for my shrimp tank. The tablets stay in place and the shrimp are more vibrant. No fish seem to be affected by the lack of dyes or preservatives.

I’ve used this for several months now. My snails are eating them and seem healthier. The tablets are easy to place and don’t fall off during feeding.

The tablets work, but some fall off after a few days. I have to reposition them regularly. Still, the spirulina content seems beneficial for my herbivorous fish.
