@IHOctopus They are definitely shoalers at least with a school of a dozen. If you add more, they may school, but I’m not certain. I would say a medium flow, but definitely nothing too strong. You also may want to look at Select Aquatics. Greg Sage has the premier Odessa Barbs, they are unmatched and I’d never purchase them from anyone else. He has taken years to perfect his line, and holy wow, in person they are stunning. Good luck.
