I'm not thinking about the long run as the Oscar will be moved to a bigger tank in the future. My girlfriend wants to get me some new fish for my 55 that I currently have and I've wanted a couple clown loaches for some time now. The only question I have is if they clown loaches will be fine with the oscar. The oscar is only about 1 inch right now and the loaches will be about the same size. The oscar will get moved when he gets bigger so I'm not worrying about the "when it gets bigger" scenario right now.
