Need a stocking suggestion

[dprUsh83]

I am going to my LFS later today and I'm thinking about picking up another fish, but don't know what to get. Right now in my tank (150 gallons) I have:

2 Oscars
2 Plecos
1 Jack Dempsey
1 Senegal Bichir

I want something that will get big, grow fast, and look good.

What do you guys think...any recommendations? The LFS doesn't have anything too elaborate, but I figured I'd grab a few ideas before I head up there later tonight.

Are you worried about aggression? Maybe check out a Jaguar Cichlid and see if that might fit your bill

Jags would be cool. You could geet Texas or Firemouths as well. What is he plan for the filtrtation?
