indo tiger attack hb arowana

[ROY1204]

Hi everyone, I have a issue about my 6" indo tiger and 7"arowana. indo tiger was in the tank first and later on, I bought a arowana into the tank. once I put them together, tiger attack my arowana (5") . So I bought a divider to separate each other. in the tank I also have 3 parrots and 4 silver dollars. they are all with tiger before and no fighting except my parrot sometimes attack my tiger too... after a month or 2 months, my arowana grows up to 7 inches.. and I tried to take out the dividers and looks everything ok for few days. but one day I woke up I saw my arowana got hurt. So what should I do with them.. or keep separate them until my arowana get bigger? I like both of them. thanks
