Used Book in Good Condition
I am too excited about this so I figured I'd share with all of you. It looks fascinating and the reviews are great. I can't wait to read it!
Oh, and George is in the background. I had to step back from the tank because apparently he did not like pictures of the fish on the cover and whenever the book got near the tank he would thrash the water surface. Maybe it's a South American / African feud thing.

The circling behaviour, or "carouselling" is one of a series of escalating steps cichlids use to assess the size/fighting ability of their opponents. Pretty much, the fish start by looking at each other, and if one is clearly bigger, the dispute ends. If they're similarly sized, the bout will escalate into some series of gill flares, carouselling, and finally jaw locking. By doing this, the fish are able to prevent wasting energy/injury unless they really need to - i.e. they are actually really closely matched. If you're interested in this stuff, I strongly recommend reading "The Cichlid Fishes" by George Barlow. It's an easy and really interesting read.
