Hey everyone, I am heading out of town and would like to know the best/cheapest way to keep my fish fed. I currently feed them frozen brine shrimp, but am thinking switching to the flake or pellet food. I have seen things like the Banquet Feeder, where it is just a time-release feeding block, but it says it is mostly for bottom feeders. I have a royal gramma and Cardinalfish, plus lots of cleanup crew. Would the feeding block work? Or should I bite the bullet and go for an automatic feeder?
