Food for fish living in different levels in the Aquarium

When food is added to fish.  The food may float in the surface of the water.  This makes the food available to surface fish which stay in the surface.  However, there are many species of fish which do not come to the surface.
These fish will not get food.  Hence, when feeding it is necessary to choose your food depending on the fish you have.  Sinking Food is a special type of food which sinks once it is dropped into the tank.  This ensures that middle level fish also get a chance to eat.

There are different types of sinking food depending on the rate of sinking.

If you have nocturnal fish, drop some food before switching the lights off.  This will ensure that the fish which forage at night will find food.
