Banner Fish

Banner fish are seen at many sites on Koh Tao but usually in pairs rather than schooling.  Banner fish often get confused with Moorish Idols which look quite similar. Moorish Idols are very raley seen here though so it's almost a certainty that a fish looking like this here is a banner fish. Banner Fish are part of the Butterly Fish family but we love them so much we thought they deserved their own page!


Banner fish are common fan favorite with their funky trailing banners, like cool hair styles and they are not so shy around divers.  With their little protruding mouths as well, it’s as if they are constantly swimming around saying “Ooooo, what’s that lunatic with the steel shell staring at?" This is perhaps until they notice you have a camera and generally starting flapping around in front of you, showing off and trying to make their way into every shot.  Cheers Banners look forward to seeing you again, and again and again.


Talking of photography, I would confidently say you will never be disappointed with the Banner fish population on Koh Tao, there isn’t a dive site here that hasn’t got it’s posse of Banner fish.  Usually coasting around the corals and rocks in pairs, they can sometimes be sighted in little gangs of maybe 6 - 8.
