why wouldn't you want an oscar?
once they mature they have awesome colors, as well the personalities they can posess are very unique, I have a relative who is a breeder for them and Angels, and some of his adults are just amazing.
I had considered making it a smaller variety s. american tank, but they just don't grab me the same... I don't know what I'm going to put in there now, so back to the thinking.
p.s...
Not to defend my previous standpoint, but I did research the net, and there are quite a few places that say one oscar was ok for a 30 gallon, I'm not saying they are right, just pointing out I was mis-informed(hence my response).. perhaps adding realistic tank sizes to Aquarias fish profiles would make that part easier for newbs to get good info..
I joined this site because it seemed to be the biggest and friendliest, and honest. which doesn't mean the best by default, but its a good start. thanks again for your info.
