I currently have 4 discus of the following sizes..... 2cm, 2.5, 4 and 4.5. The 4cm chases the larger one and the larger one chases the 2.5 and they seem to leave the little one alone most of the time.
Today i am receiving 6 large adult discus. If i leave the two small ones in the tank will they be picked on by all the large ones or will, because of the increased numbers, there be less interaction? I can separate the two smaller ones into a tank of their own and grow them up. Would this be preferable?
