Okay, so everyone wants to be able to sex Banggais. I know I'd been certain a few times I knew how to do it, and was foiled each time. Here's a new idea. I noticed that for every pair of Banggais that I have, only one will eat the Ocean Nutrition Formula II frozen food, and it's always the female. The males take it in and just spit it back out.
It's just like with humans, the women will eat salad and the men all want steak.
