The Big Blue Groper Fish is not a real "groper" but is a member the wrasse family. The Blue Groper is usually found on exposed reefs to about 40m deep. They range from Wilsons Promontory in Victoria up the east coast to around Hervey Bay in Queensland. At most dive sites in Sydney, the banging of two rocks together will usually attract a Blue Groper (he thinks you are getting him something to eat!).
APPEARANCE
The Blue Groper male is the big blue fish that we all know and regularly see. The males also have orange lines radiating from their eyes. Look closely next time you see a Blue Groper while diving and see if you can notice the lines. The females are smaller and range from a brown colour to a reddish brown; they may also have a series of pale blotches along the side of their body. Juveniles start out as a green colour and then change to the brown of the female. The fish also has very large lips. It grows maximum size of about 1m.
FOOD
Blue Groper love sea urchins, as most people would know. Please do not kill sea urchins to feed to the Blue Groper, no matter how tempting it may be. The sea urchins have their place in the reef ecosystem too. They also eat small crustaceans.
Sexual Activities
SEX CHANGE: The most interesting fact about the Blue Groper is that they start life as females and change into males later in life. So a particular blue groper could breed as a female one year and then the next year turn into a male! Little is known about the factors that trigger this sex change, however it is believed that they appear to change sex when they reach a certain size and age, or if the local male is removed from the reef the next-biggest female will change to a male. It is also believed that if there is an increase in the female population a female may turn into a male if the threshold between the number of males and females is exceeded.
REPRODUCTION: The Eastern Blue Groper spawns over three months, starting around July and finishing up around October.

For this dive you must be confident in the water. This site is one of our favourites and is usually conducted as a drift dive with the incoming tide. It is a bit of a clif walk down, you need to be confident in the water. Step off the rocks into the big blue and let your self be taken along the wall, looking for weedy seadragons, rays and Pj’s. Its always good to get to the site early to get set up and then park your car at the exit point. The second dive will be held at The Steps.

a beautiful dive at cronulla called oak park at Jibbon Street Cronulla. Oak Park is a relatively shallow dive (max 11m) but the site is massive with a large range of marine life, from cuttlefish through to schools of Old Wives. Whether you are just starting out or an experienced diver, it is a great site for everyone.
