Andreas, I have seen Snooks some years ago at the Car Pile (Dive Bus reef); I agree, they are quite rare. Yesterday my buddy and I found a large Moray Eel resting under the pier at Baya. The eel is at least 6 feet long; apparently I disturbed him because he started to look for shelter; seeing this large eel swimming was quite an impressive sight. Where he found it I have seen him several times before, so it is a regular guest. This was the first time that I saw him swimming free.
