Hi, I'm going on a 4 day holiday and I'm driving there at 9:30am tommorow. Its night time in Sydney right now, and my lfs opens at 10. My neighbour who has never kept fish is coming to feed them, I put food in ziplock bags so she doesn't over feed them. Are there any alternatives, its 9:00pm in sydney currently, so I can't go to my lfs now. What should I do?! I ran out halfway between a 50% water change, my aquariums only 60% filled up. Any help would be appreciated
