I've had an Oscar for a little over a year now, he has grown to about 10" so far. I would really like to put some other fish in the tank though. I probably should've put some other fish in with him in the beginning while he was smaller as he will probably try to eat any tankmates now. But, I'd like to know what I could put with him, I've considered the pleco, jaguar catfish, or pictus catfish. Also, I read that you could put tinfoil barbs with them. I have a few medium sized ones (3-4"). So, what would be a good choice OR what do you have with your Oscar?
