Rohu or (rohi) relies on phytoplankton when they have grown to adulthood. Whale sharks are also surface food eaters.
Surface water refers to lakes, rivers and other bodies of water. It is usually filled with fish and other animals. Groundwater is the water that lies under the ground.
If the water surface is frozen, fish continue to swim.

Yes.
Before a storm, there is very little dissolved oxygen in the water, so fish rise to the surface for oxygen,which is more plentiful near the surface.
there is many adaptation fish have to survive like they have gills to breath under water and a fin to swom better
Some fish are surface fish and others are not. Without you saying what kind of fish it is that is at the surface it is impossible to say if anything is wrong. BUT! if the fish are breaking the surface and gasping for air, then you have a major water problem and need to do some very large water changes immediately. Otherwise your fish will die.
