Yep, it probably isn't ich. It is probably a transportation/handling injury. It could also be fungus or a secondary infection. Treat the tank with Stress Coat and keep an eye on the spot. If it gets worse, then that is a good indication that it is fungus. If more spots apear, then it is certainly ich. It is a good practice to use aquarium salt with each water change. Ich and many parasites can't tollerate salt. Also aquarium salt has trace minerals and electrolytes to help healing.
