Just started my pico tank last night, and I got to thinking that since this tank will be mostly rock and corals, maybe one fish, or one anemone, or a hermit crab and shrimp.... since corals are live, rocks are considered live, and the others are not really fish..... what should I use to feed them and how often? its easy to feed a fish only tank or even my dog, he is probably the easiest to feed.... he will let you know when he is hungry especially if you feed him a few minutes late, he starts barking until he is fed.
