Thanks for the kudos guys!
Elliot: i can't tell you how much i salivated over the Nikonos RS! Is it really as good as it seems to be? I'm hoping the G9 is powerful enough to produce good images and be useful for many years to come.
tor101898: i'm using the canon WPDC-21 housing without any lenses or strobes (at the moment!) The ikelite was just too bulky and heavy, and didn't really offer enough advantages over the canon housing to justify it.
melev: Thanks so much for your continued support! and yes, that is indeed bluey. He really is that blue, it's quite startling.
coraljunky: thanks! I have seen crown of thorns, the grand total of 4. there are a couple of shorts of them further back actually, and they are quite surprisingly beautiful when you look closely. They really aren't the huge threat to the reef that some people have suggested, they are just a part of the reef system. Parrotfish are far, far more destructive with corals, but its just the way it works. Huge outbreaks can be an issue, but the natural balance (assuming we haven't messed with it!) will ensure that the populations remain relatively constant.
Anyone with an sps tank can attest to the rapid growth rates corals are capable of, so as long as the environmental conditions are not adversely altered, the corals can take care of themselves no problem.
(p.s: not a stupid question)
I've been snorkelling recently, and have some shots to share (including some of a giant cuttlefish). So stay tuned!
