Interesting Quotation

[Quinn]

Found this in one of my texts, kinda neat: "A cost-benefit approach to territoriality requires that we consider the disadvantages of aggression, one of the most obvious of which is the time cost of the behaviour. A territorial surgeonfish, for example, chases rivals away from its algae-rich turf on a Samoan reef an average of 1900 times per day." So I guess we know why tangs are such bums in many cases. (Imagine doing the data collection for that research.)

I wonder if they are referring to a particular species or all tangs in general? They mention a specific reef so I would be inclined to think they mean a certain fish. Any ideas which one?

Here's the other side of the page, Acanthurus lineatus (clown tang). However it may be a stock photo. There are a fair number of species of tang that live in Samoa.

I have no trouble believing that of a Clown Tang.
