The mandarin is very private, you never see them on a regular dive, you have to wait around 5 pm - 6 pm to get the lucky shot of the mandarins shaggin. It's a pretty spectacular experience and a very different dive than what you normally do.
Staying in one spot almost the entire dive. But well worth seeing, IF YOU KNOW SOMEONE WHO KNOWS WHERE THEY ARE!:)
In a place... DARK enough for Bats to sleep, DEEP enough to make my heart beat, TIGHT enough to hit my head on the cealing, COLD enough to pis my wetsuit, EXPENSIVE enough to empty my pockets and the WORST of all, ADDICTIVE enough to come back to!!!... THE PIT - DOS OJOS.
