Blow the conch around suspected mermaids and see their reaction.
They come up to you and make dolphin sounds, which is both hilarious and a dead giveaway.

As @Naemi_Han said, blow the conch around one and then you get a new option to ask them why they reacted and then they will admit to being a mermaid even without high relationship.
