Do we actually know this? Is it, perhaps, an assumption made by the people who should know better which has now passed into folklore and has become fact?Comment

Doesn't look like a colour change to me - looks more like the camera was exposing for the bright background initially so the fish was dark then it corrected itself and exposed for the first in the latter part.Comment

It's pretty common once you start watching out for it. Otherwise you think they come in two colours.
And I've seen it a bunch of times with no cleaning happening.

You may find that I didn't because I bastardised the quote, which is at least part of the reason why I apologised to Mr Shakespeare.
My other problem is that I am completely blind in my left eye and the other one does get tired, as it was last night.
The thing that really worries me however is why you have responded as you did. I was pretty happy with that original message of mine, I thought that it was fairly innocuous.Comment

They can be territorial so were probably changing colour in response to you, the diver, as oppose to the cleaner fish.
