This is a handy sized reader by Scott w. Michael. I have seen a few people with it and Liz dug it out a few times today...So I picked one up at Reefer's Aquatics <plug> . Nice pics and some info to. Certainly not an exhaustive guide , but seems to be a good all around quick guide for common marine fish.
The perfect size for bathroom reading
That is just in case someone wants to borrow mine and not pony up and get your own !
