Ornamental fish industry is now becoming highly competitive and keeping ornamental fishes now is a worldwide hobby. However, fishes, especially of salt water, are very delicate and there are many factors affecting their growth and survival. One of the top reasons why aquarium fishes die is due to overfeeding, improper, and poor water quality. And attending to these problems is tedious and time consuming. By creating a system that would automatically feed the fishes and maintain water temperature and salinity, the fish owners won't need to worry about feeding the fishes or worry about the temperature and salinity of the water. The functions of the system are controlled by a single microcontroller. The automatic feeder uses a rotating scoop to dispense fish feeds of about 78mg every rotation of the feeder. The chilling unit maintains the water temperature between 24-26 degrees Celsius by automatically turning it on and off as needed. When salinity/specific gravity of water goes up to 1.025, the system adds a few amount of water every minute until the specific gravity returns to normal. The system has water leveling function to prevent under and overflows. The system can also automatically prepare salt water and make partial water changes. Through this system, manpower used in feeding the fishes or maintaining water temperature and salinity can be completely eliminated. For fish breeders and retailers, cost can be lessened by replacing some of the employees with the use of the system. And for pet owners, this system can eliminate the time and effort needed to feed the fishes and to maintain water quality.
