Something else that should be mentioned is that it's all relative to other factors such as feeding and also the particular line of coastal. The coastals that I work with tend to stay on the smaller side, and I feed conservatively too. For example here's a female on a clutch of eggs in a CB70 tub for size reference. This is an older female who's had multiple healthy clutches. So I'd say that a fair range would be 4' - 10'+
