I add a copper tiger oscar in my tank wid my 2 old albino today.they seems a bit angry. Sometimes they r running after my newly added guy. By size they r almost same.may be d difference is only 1/2 inch. Bt I'm worried of my albinos lil aggression.wil it be ok by time? May be after 2 or 3 days? Or is it harmful for my newly added buddy. Please giv suggessions.all opinions r most welcome... thanx
