I have a Albino Oscar. He's killing everything in my tank. I have a 150 gallon that I built a partition to seperate the smaller fish from the big guy until they are about the same size. and somehow he ate them all. Some got brave and were able to swim across and never made it back. some he waited till they got close enough to the screen and he somehow get a hold of them thru the sides. I have had it with him. He's costing me too much money. I'm thinking of giving it away. Unless someone has any suggestions.
