A mixture of coral reef fish swim past at the Cairns Aquarium.
Imagine coming home after a long day, seeking peace in the gentle dance of your aquarium fish only to notice something feels off. The bright colors seem duller, the swimming less graceful, or perhaps your fish is hiding more than usual. While fish may not bark, purr, or whine, they have their own subtle language. The truth is, fish feel stress too, and if you're not paying attention, you might miss the signs until it’s too late.
