My fish don't seem to like their food
I have 30 Ember Tetras (added over the last months in 3 groups of 10).
I feed them Ken's Premium Tropical Fish Flake, but they are not really super interested. Some might come to the surface and pick up a flake, but most seem to ignore the food. There's definitely no rush to the surface to get fed.
In my past tank experiences I always saw fish rushing to the surface as soon as the first flake started to hit the water.
Is it the food? Is it the fish?
