i have a 125 gallon tank that i blocked off for my oscar that was getting beat up by my green terror........and the oscar bounced back and hes all up to typical oscar behavior beggin for food when i go by the tank and i think has a lil size on him......but i was wonderin when a good time would be to take out the barrior and see if the green terror will be him up again or not...cause id like to give the oscar more swimming room.......or is their anything else i should try?
