• Most divers would already know the Eastern Blue Groper. The Blue Groper is the largest reef and most well known fish in the waters around Sydney.
• The Blue Groper is usually found on exposed reefs from about 0-40m deep
• The banging of two rocks together will usually attract a Blue Groper (he thinks you are getting him something to eat!).
• The fish grows the max size of about 1m.
• The most interesting fact about the Blue Groper for me is
• that all Blue Groper 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!
• Blue Groper has been known to live as long as 35 years
