Currently I have 15 medium tiger barbs and 3 filament barbs (about 4 inches) in the tank. Everyone gets along.
I tried adding a few Roseline Sharks that were the same size as the filament barbs, and it did not go well. The filament barbs would not stop chasing and nipping the sharks.
I am wondering what I could add at this point given that the Filament Barbs seem settled and aggressive. Someone suggested a Severum that is bigger than the filaments. Someone else suggested Blue Arcaras. I was thinking another school of a different kind of tiger barb.
Any help is appreciated!
