Any recommendations on auto fish feeders? We're planning on a summer vacation with friends and won't have anyone to feed our marine fish while we're away because the people who would normally take care of our pets are traveling with us! And since we normally take care of their pets while they're away they are going to need such a feeder as well for their freshwater fish. Our need is feeding them once a day, every other day. We normally use frozen brine but will use flake whilst away (what they originally started on), if that matters. All I know is that battery powered is preferred over AC, in case of power outage -- highly unlikely and then the pump would fail and the lighting would fail and zombies would over-come the house and we'd come home to smouldering ashes. The End.
