I alternate feeding the fish pellets and Rods. When preparing the Rods, I thaw it in a cup of tank water and then pour it through very small net into another cup. During feeding I dispense about 2-3 mls in the the 150 tank. As soon as. It goes in, a few sps colonies begin to release strings of mucus from the polyps.
