An automatic fish feeder is an electronic device designed to feed your fish without you being nearby. One automatic fish feeder will work on all of them.
Fish feeder framework is structured as a mechanical and electrical gadget that administers appropriate measure of nourishment to the fishes at an accurate time interval as planned by the farmer . A programmed fish feeder is essentially a component that delivers an endorsed measure of feed to the fishes at wanted time interims. The main importance of programmed fish feeders is that it lessens the labour force required in manually feeding the fishes. One key element of programmed feeders is a form of programmable gadget that enables the administrator to vary
the recurrence and measure of feeding . This could be a mix of electrical and mechanical parts that release feed into the fish pond. Some concepts utilize electrical clocks to sequence the release of feed. Most often, smaller fishes are fed several times within each hour, and bigger fishes are fed on hourly basis. Programmable feeders utilize some sort of mechanical or pneumatic conveyor to spread the feed to the fishes .
Several automatic fish feeders have been built in the past few years to ease the work
requirements in fish production. Sakshi Nirwan et al.,  used Arduino Uno in the design of an automatic fish feeder system. The device is able to dispense fish food at different time intervals with precise amount of food. Also the device can be programmed to guarantee that the feeding plan is followed accordingly.
BENEFITS OF ELECTRONIC AQUARIUM FEEDERS
Fish are not to be given too much food. It is estimated that fish should be given as much as they can eat in 3 to 5 minutes, and once a day. However, the electronic fish feeders prevent overeating by releasing the right quantity of food, at scheduled times. This way, aquarists who have to get away for few days do not have to ask their neighbours or friends to come over and take care of their pets. It is often impossible to find a reliable person available and willing to do such a favour. The electronic fish feeders are therefore a solution for fish keepers who own aquariums and which ensure that the pets are fed in a healthy way and on schedule. There are multiple chambers within the electronic fish feeder when the feeder rotates (clockwise); the food is released at a set time. With the help of the feeder, feeding mixed food to the fish, including fish flakes and fish pellets, becomes more manageable. The mounting system is typically in the form of hooks or brackets. However, some electronic fish feeders also come with suction cups that attach to the wall of the aquarium.
Though some feeders are designed specifically to keep food dry, many designs allow moisture to seep into the food hopper. This can cause clumping, and can result in the failure of the mechanism. Because fish feeders generally cannot feedfrozen or livefood, they are not effective options for feeding mostpredatoryfish.
Maintenance of electronic aquarium feeders
The maintenance of electronic aquarium feeders basically consists in keeping the device clean and making sure the electronic part of the feeder does not get wet, which may cause improper functioning.
