Coralliozetus rosenblatti, known commonly as the Spikefin blenny in Mexico and the United Kingdom,[1] is a species of chaenopsid blenny in the genus Coralliozetus.[2] It is found in coral reefs in the eastern central Pacific ocean.[2] It was named by John S. Stevens, jr., in 1963,[3] and can reach a maximum length of 3.5 centimetres.[2] Blennies in this species feed primarily off of zooplankton.[4]
