Hey Polar, I'm probably one who jumped in and hammered, but I hope it was in such a way that it wasn't a personal attack on you.
In my opinion a green moray is something that ought to be barred from sales in the stores, just as 99% of the people who buy reticulated pythons have no business having them.
For every person like you who knows what's coming, there's 25 who can't screw in a lightbulb, and these folks NEED to be discouraged.
As for making the save at the LFS, good job, by the way....I just did the same thing with a little Gymnothorax saxicola, a bunny compared to a green, but when I caught my first one that "bunny" bit halfway through my finger!!

Re your green, I was almost killed by an 18 foot reticulated python that had been purchased and raised by a walking blonde joke, and once I survived (barely) the episode, I turned them in to the SPCA, who got a court order and removed it.
It was just a miracle the snake hadn't gotten one of their small children!!
The poor snake hadn't been fed in almost a year or even watered in close to 6 weeks, and was in a cage 5 feet long, cruelty in anyone's books....the tip off came when I was laying on the floor, wrapped in it's coils and with the jaws locked on my wrist (one of those moments where time slows to almost nothing).....as I watched the blood gushing from my arteries the damned snake was drinking (make that gulping) it like there was no tomorrow.
With an 8 or 9 foot green moray the liklihood of something similar is just too great.....if one of them crawls out and a small child finds it before it perishes, the results will definitely make the headlines" and certainly NOT help the public's eye view of our hobby, the way really stupid LAWS get passed by legislators who don't know a cow from a whale.
Just to show I DO understand about rescues of this sort, though, here's photo of an old pet of mine for you...recognize the type of animal?
His name was Ghost.
