I started this hobby because a friend who has an 14 inch. oscar, he looks amazing, very quiet and calm... i didn't star my hobby with an oscar, i decided to start my hobby with bala sharks... they are good, look good, i love them but you cannot even try to interact with them, they get scared with just a little movement.... i had a bala shark over a year, he got big, but i quit with them, and i decided to go with my biggest inpiration, to grow up an oscar and make him a fish that you look and be amazed.... i bought an oscar 4 months ago very small about 1 inch, now he is almost 3 i think... and every time i get near the tank of when i clean it up, i'm not affraid for him to jump up of fear as a matter of fact he always try to be near me, maybe waiting for some food...
Also i suggest that if you are going to have oscars, have 2 or 3 small tanks with platies, or guppies and breed them, to have occasional fresh live food for oscar... you will love to watch them chase and eat their food....
