Hey Mike...Even without the red or blue hook coloring developed, you should be able to tell if they are one of the two. The red hook bars are super thin and the blue hooks are thicker and more blotchy. If the bars are thicker as you mentioned, they are probably the blue hooks. Though the finnage coloring is not so pronounced at the size, the shape is very different as well. I have grown the blue hooks out to 12+ inches before I sold them and now have some 3-4inchers as well. There is no doubt that they are the same fish though...even with almost a 10 in difference. If you think your smaller ones are the blue hooks, they probably are. Post some pics when you get a chance and we can provide a more accurate assessment
