I am getting a new twenty gallon and want to turn it into a planted barb tank. Online I have found some conflicting info. It says in some places tiger barbs cannot be mixed with cherry barbs or harlequin rasbora and in others it says just the rasboras can't be mixed with the tiger barbs. But these are the fish I am trying to choose from tiger barbs, rosy barbs, cherry barbs, or harlequin rasbora however there will definatley be a bristlenose pleco in there. So if anyone can tell me good or bad experiences with mixing any of these or if they know which ones can be mixed that would be greatly appreciated.
