Okay, so I have a question about automatic feeders. I'll have to do some traveling around the holidays. I'll be gone, at the longest, 4 days. I'm thinking of getting an auto feeder. Any recommendations? I feed frozen right now so I'll have to try different food. How will the gel food work in these? Will it work in these? I have a sample of the Instant Ocean Seaweed Blend that came in my bucket of salt and figured I'd give it a try. Any recommendations for a dry food to use with these? Again, I have a sample of Nutrafin MAX I can try out. Anyone use an auto feeder? I only have 4 fish. 3 Green Chromis and one small clown. 20 snails and 1 sandsifter starfish too.
