What our visitors say:

“Great aquarium”

The Solitary Islands Aquarium is only a small aquarium but it's very informative and the tanks are beautiful. Our four year old son had a great time searching for the creatures.

“Very interactive”

We spent about an hour and a half at the aquarium. Very interactive and the staff are incredibly informative. Highly recommend to break up a long trip.

“Perfect family activity”

This is a great activity for the holiday visit to Coffs. The kids get to see feelings and touch sea creatures. An informative movie is great to learn about the regions marine ecosystem.

“So beautiful”

It's amazing to see all the fish and sea creatures they were all so colour and it was a great day with the teens as well, so it was fun.

Solitary Islands Aquarium

1 day 17 hours ago

In a new installation at the Solitary Islands Aquarium, we display the amazing attributes of corals that flouresce.

Unlike fireflies, glow-worms, and other bioluminescent creatures, these brilliant corals don't glow on their own. Instead, they absorb one colour of light and emit light of another colour, a process known as fluorescence.

Many corals are intensely fluorescent under certain light wavelengths. Why some corals fluoresce is not fully known and is a subject of much study.

In particular, shallow water reef-building corals that fluoresce seem to be more resistant to coral bleaching than other corals, and the higher the density of fluorescent pigments, the more likely to resist bleaching. This enables them to better protect the zooxanthellae that help sustain them. The pigments that fluoresce are photoproteins, and a current theory is that this acts as a type of sunscreen that prevents too much UV light damaging the zooxanthallae. These corals have the photoproteins above the zooxanthallae to protect them.

Corals that grow in deeper water, where light is scarce, are using fluorescence to absorb UV light and reflect it back to the zooxanthallae to give them more light to turn into nutrients. These corals have the photoproteins below the zooxanthallae to reflect it back.
