Sorry my first post not sure if I did this rite. My question is about what size will the trimac start showing its red behind gill plates. The trimac I have is a inch and a half and not showing any red yet. Would post pictures but not sure how to do it yet. I love reading everything I can on the site but never have made a post. Hope this is ok to put on here. Also would like to see some pictures of some juvenile trimacs if u could post some
