A coral holder resides in an aquarium and includes shelves with holes which accept coral plugs. The coral plugs are small round tables with cylindrical stems extending down from the table. Hobbyist take adult size living corals and “frag” them (i.e., cut the mother colony and break off a small section) and glue the coral fragments to the coral plugs. The coral plugs are inserted into the holes on the shelves providing a coral display. The holder includes a center section, a fixed top shelf and adjustable shelves. The adjustable shelves extend out sides and front of the center section and are adjustable allowing the aquarium owner to adjust the adjustable shelves accordingly to their needs (i.e., for the number of coral plugs). The positions of the shelves are fixed by inserting the coral plugs through the fixed top shelf and through the adjustable shelves.
