Well, young Oscar is now about 2.5" and seems to have decided to supplement his food intake with some live fish!
My four Cardinal Tetras are now two and tonight I found one of the larger Tetras beheaded! I know I am putting two and two together and making four but I think it's a safe bet.
I'm surprised how soon (and how small) he has started this - oh well, time to move the little ones to their new tank.
I notice Oscar has started chasing the two Silver Sharks which surprises me as they are both much bigger than him. Should they be OK? I don't have a tank big enough to move them out.
