I have a good suggestion for you from previous experience. Throw in there an oscar. The only thing I would worry about if i were you would be filtration. since you want to go with a big fish, wichever you choose, there will be alot of waste, so think about good filtration

This guy is funny!....i think....
Well, im not sure if he is joking or not so just in case you arent 100% sure, Oscars are a BIG no no!
