ADA’s Automatic Fish Feeders for aquariums can only feed fish twice daily. You only need to press a button, once for a 12-hour feed and twice for 24 hours. It’s a simple and barebones setup that works as described, but it’s not suitable for feeding fish that need more than two daily feedings.

The humidity and moisture due to close proximity to the water can also cause this type of problem with an electronic feeder. Second, one has to make sure that the food containers are properly sealed and the food is kept fresh. At this time electronic feeders are not able to adjust to the changing needs of the fish over longer periods which may result in either overfeeding or underfeeding.

By design, the feeder needs to sit above the fish tank over an opening.
