Well my 300 gallon tank was turned into a battle field today.Everything was great,everyone was pals,until now.My 28 inch silver arowana battled my 20 inch super thick GG,I walked in at the beginning i suppose so i was lucky to have stopped it.The GG has a huge mouth bite on his back and the big sliver lost a huge scale.I had to move the GG out of the tank.I got water everywhere!I also noticed my pink GG beat to hell in the corner of the tank.The pair of O's are even fighting??What the hell happened?
