Ever wanted to go away for a few days and not worry about the neighbor feeding your fish or your fish going hungry? Here is the thing. This is a simple DIY demand fish feeder from some easy to get items. Before we get started I would like to make a few points about feeding and possibly a few risks of using this method that will be of use to you.
These DIY demand fish feeders are great for most species of fish, however there are always going to be a few that are “dumber” than the others, so they do not take to it so well or as fast. This is where some perseverance will be needed while training the fish to accept taking food from this scary thing hanging above them. If the fish do not take to it after several weeks, you will want to upgrade to programmable shaker type feeders or find an alternate way of getting feed to your fish. A belt feeder would be my choice.
