Sweet size! That's what I'm looking into getting for an upgrade!
Oscars, from what I have heard, are very intelligent creatures that are amazing to have. Personally I don't like the way they look when they become full sized but I'd love to have one because of their personality. The whole boringness of oscars is completely wrong, I've heard that they're interesting fish to own; however I have never had one so someone with personal experience would have to chime in for further knowledge
As for the community, you can't go wrong there. I can sit in front of my community for HOURS without getting bored. I just love watching all the different fish school!
So either way you're great!
