Not all bull reds are female. I had some guy try to tell me a while back that all the big bulls would have eggs in them, boy was he wrong. He pulled out the stomach trying to tell me it was an egg sac, I cut it open and told him that he was a fool! The egg sac is easily visible!!! The males can also get very large, I caught quite a few big guys that were full of milt a couple of weeks ago.
