Indian Triggerfish dig their shelters under solid objects by swimming sand away. This is done by putting their mouth against a solid object and swim like crazy, thereby creating a current that takes the sand away and making a little nest area.
Triggerfish have a hard spine Dorsal Fin that can be locked.
When sleeping this spine is used to wedge them into place in a crevasse and so deter predators from pulling them out of their bed!
The spine is also held erect as a warning to other fish to stay away.
Several large Titans blow shallow depressions in the sand for nesting and if approached will raise this spine as a warning, if ignored they may charge, even divers! especially the Titan Triggerfish who will take a tasty bite!! Beware!!! Ref: https://www.fishbase.se/summary/4279
