A Swarm of Fish

I have been watching a series on the BBC about "Swarms"...they have some amazing footage of swarms of fish, birds and insects and talk about the behavior of the swarms as a whole....really interesting stuff. I couldn't help think about that series when I saw this school (swarm) of fish around this reef head. They all acted as "one"....really amazing stuff...

Is this photo too "tall" for your monitor? It fits nicely on my iMac, but don't want you to have to scroll up or down to view it...let me know in the comments if it is too large, and next time, I will re-size photos like this...
