Xenisthmus polyzonatus

Xenisthmus polyzonatus (bull's-eye wriggler or polyzonate wriggler) is a species of fish in the Xenisthmidae (wriggler) family, which is regarded as a synonymous with the Eleotridae.[3].. It is found in the Indo-Pacific, from the Red Sea to Samoa, north to the Ryukyu Islands.[4]

It is golden-brown to orange-brown in colour with approximately 10-12 irregular pale-greyish bars along its flanks and a small black spot with pale edges, like a bullseye, on the base of the tail. The spots on the dorsal and caudal fins form irregular stripes.[5]
