Jim, I trust that your "short" vacation went off without too much drama [although I suspect by your comments you'll be glad to get back to work so you can have a rest]. You have a small grotto in the coral, that would be ideal for the head and first few inches of the body of a Moray Eel. I thought in your "spare time"
the image of a Moray shooting out to try and grab a fish would be interesting.
The attached is some basic info on them for anyone interested in what they are ....
Keep up the brilliant work Jim.
