I thought typhoon #16 is far enough, but it wasn’t.

Although we were planning to go to the Manta Point today, the wind was too strong and the swells were too high 🙁

We are sorry for the guests who were looking forward to meeting mantas…


So we went to places where it will not be affected by the wind and swells.

Lucky we have corals and beautiful fish everywhere 🙂




Working hard to blow fresh water to the eggs.

You can see the eyes of the babies inside the eggs!


Tiera Batfish and Longfinned Batfish.

They look similar, but different.

Longfinned Batfish has pointing mouth, whereas Tiera Batfish has round mouth.


Longfinned Batfish is called “Akakukuri (red-bordered)”, as it has red border when it’s a juvenile.


Hope the wind will calm down tomorrow.

If we can, we  will try the Manta Point!
