Wife really wants an oscar, I rather think they are neat too. We have a brand new 4 footer 120 gallon and are trying to figure out stock. LFS has a 1 and a half inch oscar that we would want and like 4 silver dollars about the same size. The owner told us that the oscar would quickly be eating them and that really all we could really do is have an oscar by itself. We have an adult golden angelfish that would be one of the first into the tank. We figured if the oscar was well fed and grew up with his teammates he might be relaxed enough to not be a murder machine as everyone says
