Yellowmargin Triggerfish (Pseudobalistes flavimarginatus) キヘリモンガラ size 50cm
A small Yellowmargin Triggerfish. Amami 2023

An adult Yellowmargin Triggerfish. They are one of the larger triggerfish getting over 50 cm.
They have been known to attack when guarding their nests. I have not seen that yet with this kind of triggerfish. Amami 2025

I think that this is a juvenile Yellowmargin Triggerfish. I am not sure because it is very similar tto the juvenile Titan Triggerfish. I am getting some conflicting information about the difference between them. Amami 2024
