I bought an 8" water cow 2 weeks ago. It was doing well at first until he tried taking a chunk out of my 6" tiger oscar. Yesterday he grabbed right ahold of my 5" Jags head while it was fighting with the jack dempsey. I wasnt sure if it would let go. I thought it would be ok with the more aggressive fish. Was I wrong? should I let them sort out their differences? there havent been anymore problems......yet
Thanks again

thankyou so much for all your advice and helpful information
