Ever wondered how far a reef spa treatment really goes? 🐡✨

In this rare underwater moment, a pufferfish stops by a cleaning station and lets two cleaner wrasse go all in — literally swimming inside its gills to remove parasites and dead tissue.
This is trust at the highest level in the ocean. The pufferfish stays perfectly calm while the wrasse do the most intimate cleanup imaginable, proving just how important these tiny reef fish are to ocean health.
