So I stocked my 40 gallon tank with some fish (9) during my fish in cycle. Love the harlequin rasboras, super fun to watch and friendly. However.... the silvertip tetras are complete a-holes and terrorizing everyone in the tank (especially since the rasboras are babies). Aquarium store made it seem like Silvertips are passive but mine appear super aggressive! Anyone else had this issue? I constantly have to distract the silvertips to give the others a chance to get away. I almost want to bring them back to the store at this point.
