ABSTRACT:
Fish aquarium owners are enabled to feed fish during an extended absence through the use of wax-based fish food compositions. Fish food and a water-expandable material, such as clay, are substantially homogenous distributed within wax. The wax protects the fish food from spoilage due to premature exposure to water and from accessibility to undesired microorganisms, thereby enabling large concentrations of fish food to be included. The water-expandable materials expand after being immersed in the water, thereby enabling the article to become softened or to be fragmented. Accordingly, fish can ingest fragments of a wax-based block which then pass through the gastrointestinal tract of the fish without causing an obstruction.
