Function

• Homemade fish feeders automatically dispense food at a given time by a 24-hour timer. Such automatic dispensers work on a daily basis but need to be refilled manually when they get empty.
  
  

Importance

• A homemade fish feeder is vital in dispensing the correct amount of food to a specific amount of fish in an aquarium. In contrast to manual feeding, homemade feeders ensure that fish are fed at the same time daily when an owner is unable to do so.
  
  

Basic Structure

• Homemade fish feeders can be constructed by things found in your home or in household supply stores. Common components include a 24-hour timer, an empty pill bottle, one straw, some putty, a box cutter and one extension cord.
  
  

Maintenance

• Automatic homemade fish feeders require little maintenance. You just have to change the batteries on the 24-hour timer as needed and make sure that the putty still holds over time.
