The pyramid boxfish ( Tetrosomus gibbosus ) lives in the Red Sea and the tropical Indo-Pacific from East Africa to southern Japan , Indonesia and northern Australia . He immigrated through the Suez Canal into the south-eastern Mediterranean ( Lesseps migration ). It prefers coastal reefs and mostly stays near the reef base to a depth of 110 meters above sandy and soft bottoms, seagrass meadows and algae fields. The solitary fish feed on bottom-dwelling invertebrates .
