My Plecos love these tablets. They stick to the glass and the fish eat them slowly. No fish waste in the water. The spirulina helps with their color and health. Easy to use and effective.

Great for bottom feeders. The tablets stay intact and don’t break apart quickly. My catfish are more active and show better color. I appreciate the natural ingredients.

I’ve tried several fish foods, but these are the most reliable. The fish eat them without fighting. No mess, no water pollution. A solid choice for bottom-dwelling fish.
