Today is my bday and I saved up money to buy a 60 gallon but was told I couldn't, however my father suggested upgrading the 55. Im planning on a 90 gallon and as much as I say I disklike them I miss some big ole Oscar fish swimming around. I for sure want at least one Oscar although I have been following the aggressive fish trend. What are some suggestions? 2 O's are max right? one idea I had I would want three but I don't think that's a smart thing. But Salvini,Dempsey,Terrors are all some I'm thinking about. Even if something is borderline not able!
