thanks guys! update again soon! took out my big monocs already and put them in the pond downstairs... then i put 2 kelberi f1 bahias, 3 orinos from germany, and a piquiti in the 600 gallon... they are just about 7-8 inches so im hoping they make it out okay... 4th day already and no sign of aggression from the biggies... im in shanghai now for vacay so hopefully all my fish will be okay when i get back.
