Often various species are mixed together in shipments usually labelled "Borneo suckers" or "Hong Kong pleco". I'm holding out for sewellia lineolata personally :hearts:.
Mine were sold to me as Butterfly Pleco. I knew that they weren't Plecos, but Loaches, I just didn't know exactly which species. Would all of the loaches classified as "Hillstream" be compatible? If so, how many in a 30?
