Query: Not convenient for small fish

I have smaller fish - guppies and mollies. For them, the granules and even crisps (disks) are too big to swallow whole and too hard to break up. The particles fall to the bottom too quickly, before the fish can tackle them, then get lost among the gravel and rot. The granules even color the water red! I find flakes (crushed up) much better for small fish - the fish can eat them right away, and don't need to wrestle with them or wait for the water to loosen and soften them.
