See...I just learned something! re: Parrotfish...thank you! : )
And I completely agree with being friendly, open and offering tips to those who might appreciate them...a big part of my love of diving was the friendly and encouraging learning environment I had, and how those more experienced that I, were so willing to take the time to teach and encourage me. Still, I have also made it my responsibility to ask and watch and "try" to emulate those more experienced...I STILL DO! : )
What I love about diving is that you never stop learning and refining.
I also think a non-judgemental forum is a great place for those who have experience to offer it and those who wish to ask for advice and tips to be able to do so without criticism and judgement.
