These two fish need each other, they feed on algae in crevices and under rubble and while one is feeding, (with its view concealed) the other watches for predators. This means that they spend almost 90% of the time within 5m of each other. It must also mean that they share a language, a way to tell the other one there is danger OR “you go first, I’ll watch” and just maybe, in a subtle thumping language beyond our perception,
“I love you”.
