Blacksaddle Filefish copies the toxic Valentin's Sharpnose Puffer to be left alone -- same white body, black saddles and yellow tail. Look at the fins: the filefish has long soft dorsal and anal fins running along the rear half of the body, and a spine it can raise above the eye. The puffer's fins are short and rounded, set far back, with no spine, and it can inflate.

Young Blacksaddled Coralgroupers may copy the toxic Valentin's Sharpnose Puffer: white with dark saddles. The puffer stays small (11 cm), with a short body, a pointed snout, short rounded fins set far back, and four dark saddles, the middle two reaching the belly. A young coralgrouper has a grouper's big mouth and long dorsal fin, and grows into a 125 cm predator -- white with black saddles and yellow fins, or dark and covered in blue spots.
