Okay, I bought two ADFs yesterday and I'm wondering what they'll eat. So far I've tried Hikari Algae wafers with no luck, but my shrimp love them. I also have Hikari Sinking wafers, tetramin tropical flakes, Omega One freeze dried brine shrimp, and San Francisco Bay Brand Freeze Dried Bloodworms, but haven't tried any of them yet. Which food should I try?
