so i stopped a LFS and a LPS and noticed at the LFS that pretty much all their serpaes (about 6-8 i did not count them) were pretty chill but one. The one was a complete spaz, obvious signs of fin nipping on a few other fish, and when there were no fish around him he was wiggling like he was trying to swim 100mph but wasn't actually moving. Made me think of a coked up fish. Just curious what your thoughts were on this as the LFS said "I dunno" shrugged and walked away.
