no yellow tangs in Kauai??

[Namnuta]

In Kona on the Big Island the waters are literally yellow sometimes. Diving in Maui i saw quite a lot but not near the amount that the Big Island had. I know between The Big Island and Maui there is a very strong current channel running between the islands. Maybe Kauai has a similar channel between Maui that kinda isolated the islands. just a thought.
