I have always wanted oscars and hope to get a 90 G tank in a couple months. I was wondering if pictus catfish are ok tankmates for oscars? If not, what type of fish would be? Also, do oscars tend to get along with each other? I had 2 angels in my 55 G and they fought so much I had to separate them, so now I'm a little leery of keeping multiple cichlids together. Is that a common problem in angels? Thanks!
