I recently purchased some new, but smaller albino tiger barbs to go with my remaining tiger barb. the remaining tiger barb looks like he is scaring all the others to the top front part of the tank. what should i do?
Try to rearrange the decor to break up the territory. If it continues, put the single barb in your water change bucket for a hour and feed the others and let them relax, then add back the instigator when you turn the lights off.
