Great Barrier Reef marine life

Anemonefish

Anemonefish are the fish everyone recognises, and the reef has several kinds: the orange-finned, pink and Clark’s anemonefish are the ones you meet most out of Cairns and Port Douglas. Each anemone holds one family, and the fish will charge out to defend it against a diver a hundred times their size.

What to look for

Look for the anemone first, a cushion of waving tentacles on the reef, then the small orange, pink or brown fish darting in and out of it. The fish coats itself in mucus that stops the anemone’s stinging cells firing. The largest fish in the anemone is the female; if she dies, the biggest male changes sex and takes over.

Watching without harming

Anemonefish make great photographs because they never leave home, but the anemone is easily damaged. Keep fins and hands off, don’t block the light for long, and never prod the fish to make it come out: it will, on its own, within seconds.
