I got 9 from COTA in October 2018. They were about 2-3 inches. 3 Regani, 3 Bifa, and 3 melanarum. I estimate they are 5-7 inches now. I also have about 24 tiger barbs. All fish get along pretty well. The barbs and the Vieja never interact. The Vieja have a small amount of aggression among like species. All of the Vieja are very skittish. I have a 180 gallon 6 ft tank. I thought that I would have had some losses by now, that would have prevented me from having to thin the numbers, but that didn’t happen. I believe I have 2 male and 1 female Regani.
