Oscar/Jardini ..good tankmates?

Question
i have a Jardini Arowana (6" at the moment) with a Gibbi Pleco (3")...in a 20g tank...(soon to move to a 125g!)...Question: i really would like to get a Tiger Oscar and put him in with my Jardini Arowana and Pleco...will this be fine??? (the Oscar would be 4-5")...i'm just worried about the aggression thing with Jardini's and Oscars. thanks in advance

Answer
HI Rob,
 That is definitely not fine in a 20gallon tank.  You will very likely end up with a dead arrowana.  In the 125 gallon tank it would be much more possible that it might work.
