My clownfish started eating more actively after I introduced these treat tabs. The fish are more vibrant and seem healthier. The tabs stick well to the glass and the fish enjoy the food. Also, the coral in the tank has been eating the small pieces, which is a nice bonus.

I’ve used these for a few weeks now and my tang is always curious about the tabs. The fish don’t seem stressed or overfed. The protein content is noticeable, and the fish stay active. A simple but effective feeding method.

Great product for observing shy fish. The tabs stay on the glass without falling too quickly. My fish are more engaged, and the coral has started to benefit from the small bits that fall off. No artificial ingredients — clean and natural.
