I appreciate your opinion, but didn't the Dive Masters show you....
The bazillions of cool microscopic creatures that Roatan is
really best known for?
Roatan rewards those divers with superb buoyancy skills and advanced observational abilities.
If you go there only knowing how to find "big fish" and are not coached by a qualified and attentive Divemaster, your experience is quite common.
I often go to the smaller AI resort that lies just accross the channel from FIBR, but it's a
world apart in many ways. The DM is the key. With a good local guide, you should see a SeaHorse on every dive.
It's all in the picking.
Here's an interesting thread
