Cozumel does not have bumblebee groupers. Cozumel does have very large groupers though. I have been there 7 times! They will follow you the whole dive if you bring a bag of chopped fish with you and feed them
The last time I went diving there, a photographer went down with us...I got a great pic of me with a HUGE grouper (no scanner, or I'd post it). I was told it was a lanceolatus (giant grouper), but maybe not...I never even thought to look it up till now.
I wouldn't have even tried to feed it! I was told before I went down how mean the bigger groupers could be.
Come to think of it, it was probably pretty dumb getting that close to the thing.
