I gather the two big sickle-fins have been removed from the GBR exhibit?Not joining the sickle-fins! Four sawfish will be in the GBR oceanarium.
The new Tropical Bay of Rays area of Sydney Aquarium, houses the most colourful combination of Australian rays - many threatened or endangered - ever displayed together.
There are more than 600 species of rays worldwide. Rays have adapted to survive in open oceans, shallow reefs, deep continental shelves, estuaries and freshwater environments.
Similar to sharks, rays have skeletons made out of cartilage; they are identified by a flattened body with gills found on the underside of their 'disk' (body) and vary significantly in size - some rays, like the Manta Ray, can grow to 7m and weigh over 1300kg!
A variety of ray species call the new Bay of Rays home, many of which are making their debut appearance at the attraction.
It will be difficult to miss the electric blue spots of the Fantail Rays and the Blue-spotted Maskray, and with other species including the spectacular Leopard Sharks, White-spotted Guitarfish and Leopard Whiprays, the new tropical oasis is a sight not to be missed.

Stingrays have copped a bad rap since Steve Irwin's untimely death.
But aquarists say the curious and intelligent marine animals deserve a second chance.
"We really hope that people can learn that rays have a place in the world," said Libby Eyre from the Sydney Aquarium.
"That they're not these scary, big creatures to be feared."
Australian television personality and conservationist Steve Irwin was killed in a stingray attack off the north Queensland coast in September 2006.
"They have a very bad reputation after Steve Irwin but they are incredibly curious, intelligent animals," Ms Eyre said at the official opening of a new exhibit called the Tropical Bay of Ray.
The stars of the show, five tropical stingrays, were released from a bucket into a palm-shrouded bay bathed in pink light at the aquarium on Wednesday.
Native to the Great Barrier Reef, the rays are found around coral reefs and coral flats.
Ms Eyre said they would be monitored to make sure they all got on well and thrived in their new environment.
"We chose our species very carefully," she said.
"We not only look at the species and where they would occur and so on, but we transpose that into a captive situation and think 'Okay, how are they going to go in this space, how will they get along' and then monitor that very, very carefully."
So far, the exhibit has three blue-spotted fantail rays and two blue-spotted maskrays, which are threatened and endangered species.
This number will have grown by the time the aquarium re-launches in September following a $10 million makeover.
Dugongs are expected back on display in September or October, I think. Is there still a dugong at UnderWater World Sentosa? If not, the two at Sydney might be the only ones in captivity in the world now.
I have real mixed feelings about this place these days. I may be making another short trip to Sydney in September (footy finals - supporting a team from another state is expensive!) but am honestly torn about whether to go to the Aquarium and see the changes. I loved the place and don't relish seeing the Merlinisation in person.

Sentosa still has Gracie (female dugong), Jaya Ancol Sea World has a male and female, Toba has a female (lost their male a few months back). The two Sydney Aquarium dugongs (Pig and Wuru) should be back on display after 20 September when the Aquarium gets re-branded. Their oceanarium was never being renovated - the sharks were moved into there whilst the shark tank gets renovated (hence why no dogongs were left on display).
Tropical Bay of Rays is where the saltwater crocodile/mechanical white shark were. Totally out of place. It's awful but the rays are niceThe theming outside the smaller tanks is nearly complete and looks quite good.
