Automatic feeder that serves meals underwater at a fixed location. The food dispersion is controlled by the underwater food chamber. The fish are already waiting and the food cannot drift away much - everything is eaten and the water will stay cleaner for longer.

• The food is delivered underwater, through the chamber, to the same location every time
• There is very little waste from food dispersion
• Everything is eaten. No food residue decomposition in the decoration or filter
• Less pollution in the water due to reduced decomposed matter (nitrates and phosphates)
• No oxygen consumption from bacterial decomposition of food residues
• Lower food cost 
• All fish gather in one place which is ideal for checking for diseases, parasites, inflammation, and also for observing feeding behavior
