The Mimic Filefish is a filefish that has developed its body shape and colouration to mimic the appearance of the Valentini Toby Puffer (C.valentini). By copying these puffers, they appear to would be predators that they are an unpalatable meal. They are an interesting looking fish with dark brown bands across the midsection, brownish-orange spotting on the lower half, yellow fins, and blue striping running along the back. It lacks pelvic fins, but has learned to use the pectoral fins to move about the aquarium.
You can tell the difference between these filefish and the puffer in that they mimic by the dorsal spine. The filefish has two dorsal spines, whereas, the puffer has only one.
They are rarely aggressive toward other fish except those of its own genus.
They are generally reef safe, however it is possible that they may nip some coral polyps.
Their diet should include a variety of shaved shrimp, squid, scallop, mysis shrimp, freeze-dried krill soaked in a vitamin supplement, and frozen marine algae. It should be fed no fewer than three times per day.
