Arowana, geophagus, pleco, flagtail, marble Senegal, fire ill

[Adsaycha]

I have a 240 liter tank.
And I have 1 fire ill, 3 Senegal, 3 geophagus, 1 flagtail, 2 ram, 1 pleco.
Now, I m thinking to put 1 arowana and 3 or 4 shivram. Can anyone suggest me about the consequences? And any tip about which fish shall I replace if I put arowana and Shivram in that tank? Or it may be good!!

Honestly that arowana would probably be in that tank for a year or less. I'd advise against the arowana. Unless you have a tank that's 8'x3' cause that would be minimum size for the arowana.
