Stocking the Aquarium evenly

Stocking your aquarium evenly is important as it ensures optimum use of the aquarium space and a pleasant viewing experience.  Fish live at different levels in the water.  Hence, selecting fish which occupy the top, middle and lower level of the aquarium ensures that all the fish have more space.  This prevents fights and injuries.

Fish such as hatchetfish, zebra fish are top dwelling fish.  Their mouths are upturned as they feed from the surface.

Fish such as guppies, swordtails, tetras are middle level fish.  They swim in the lower levels.  Gouramis are also another popular middle level fish.

Bottom dwelling fish have mouths which are turned downwards.  These fish scour the bottom of the tank for food.  Examples include loaches, cory catfish and the pictus catfish.
