I took a month or so off from diving. Then I talked Farid into a trip. We actually had an unexpected simultaneous hole in the schedule at the hospital. So we took off to the Red Sea on a moment’s notice. How many people can just pick up and be diving in about 45 minutes? Cool! Farid led so we were at 150 feet when I looked at my dive computer. At this depth the colors are blunted, less saturated, less vibrant. This is a cleaning station. The little guy is cleaning. It’s a practical symbiosis. Where else can you get your back scratched (cleaned) especially if you have no hands to scratch yourself. Larger fish stop by and the little ones take care of business. Who figures these things out? But this is what I have read so it must be so, if it’s in print. I’ve actually seen little fish swim in and out of the mouth of moray eels. Brave aren’t they? 150 feet, this would be the limit of my dive depth for amateurs. It doesn’t feel different, just the colors are blunted.
