I have a 90 galllon tank and am planning to put two oscars in it. Question, is there a good chance the the Oscars will fight a lot, and compete for food, or will they generally be happy living together. I know it varies greatly from fish to fish, but what are the odds of the two oscars living together in harmony. I've read the 1male+1female will work as well as 2 females, but 2 males will not work. So if I am right that works out to a 75% chance of it working. Also what color combination would looke cool, for example, red+tiger, or tiger+albino. Thanks for the replies!
