Might make this a sticky...

This has some very good guides and Identification for sea-horses so you know exactly what your looking at in pet stores before buying. I have found that most of the sea-horses they are selling are miss marked.....I am currently planning a build for a seahorse tank, so I take my guide and go study sea-horses in the stores. I do appreciate the fact that most of the people say they done know if its labeled right cause they don't know much about them either. I have handed out this guide at a few stores, and they have even started checking it before labeling them. One store even ran copies of this and a few other guides I gave them to give to customers thinking of buying a seahorse.
