[Marc the Banana Wrasse is a Thalassoma the same group as the Moon, Sunset, or Lunare Wrasse. None are reef safe! Also they are not pure yellow or small! Their size is upto 20cm. You can tell if it's a Banana because they will have lines in the face just like a Lunare Wrasse or any of the others above. Also the tail and midsection have some variation in coloration typically. The yellow coris has spots in the dorsal that look similiar to eyes. On you pictures I did not see the eyes in the dorsal but saw just pure golden. Your Wrasse is stunning and has an intresting personallity but may be neither?]
