My cichlids have been eating these pellets regularly and seem more active and vibrant. The sinking feature keeps them engaged, and the ingredients look well balanced.

The pellets are easy to distribute and sink properly. My fish show interest in them, and I notice better coloration over time. A reliable choice for larger fish.
