Hawaiian ones are supposed to be hardier. They are also more white and yellow in color. For some these are difficult fish to keep. Seems like they always come in with some sort of disease and usually die during shipping or in lfs. I've had success with a few. I've always bought in 3's. They kinda school/shoal together
From a guy in Hawaii that I know that goes out diving and collects fish. There usually all around but for some reason over the last 2-3 years been fairly scarce. He's on the lookout for 3 pyramids and 3 true henoichus for me
I have a connection with a Hawaiian diver. I'll pm you his number and you can see what he can do for you. There seasonal fish so they might not be availiable until later on in the year
