Zoo Med Plankton Banquet Fish Feeding Block

Zoo Meds Plankton Banquet time release feeding blocks last 3 to 14 days, depending on block size. In addition to weekend and vacation feeding, Plankton Banquet is a great daily food source for problem feeders such as Plecostomus, Algae Eaters, Redtail Sharks, Gouramis, Saltwater Tangs, Angels & Damsels. Original Banquet blocks are also very useful for small fry which do best when constantly feeding.
