Shrimpfish, also called razorfish, are five small species of marine fishes in the subfamily Centriscinae of the family Centriscidae.

The species in the genera Aeoliscus and Centriscus are found in relatively shallow tropical parts of the Indo-Pacific, while the banded bellowsfish, which often is placed in the subfamily Macroramphosinae instead, is restricted to deeper southern oceans.

The banded bellowsfish more closely resembles members of the subfamily Macroramphosinae (especially Notopogon) in both behaviour and body shape, and reaches a length of up to 30 cm (12 in).

The razorfish uniquely adopts a head-down tail-up position as an adaptation for hiding among sea urchin spines.

[3] It is generally found in coastal waters from the central Indian Ocean to the Red Sea to Hawaii.
