Also keep in mind the oscar is going to grow at least 1" a month, possibly more.
I have 2 oscars that are now liveing in a 55gal and there getting to big for that, so now i am looking for a 125gal to keep them in. Raised mine since they were 3 inches now there 8-10 inches.
I also have a 35gal comunity tank with with a convict cichlid!, (i know your alll thinking i am crazy keeping a convict with guppies and other small fish) But its all fine, she is the smallest cichlid i have ever had and kept getting bullied by the others that were even smaller then her so i moved her to this tank and the worst she has done is nipped a little piece of tail fin off a male guppy that got to close to her eggs. She is getting a little aggresive when she has eggs (infertile because no male) so i am hopeing to move her out soon into a 20gal. (with a male)
