i'm still think it's a male. when it gets pissed off, or is in an aggro state, he kinda lets it hang out. if you know what i mean. like i said before, he had his dorsal nipped not too long ago. it's been getting longer and more pointed by the day.
most of my fish hate it as well. they get to be at least 10 in. they have been know to get well over that though. it's really hard to give a definitive answer seeing how it's a hybrid.
a very good looking female fusco!
