can u afford to get it a 100 gallon tank within its first year?

I wish the guy who sold me oscar asked me that question. Cause I would have never bought her.

Oscar turned 2yrs this month & I've spent over $500.00 on her
For meds, tank upgrades & filter upgrades, but mostly meds.

& if u do get one, keep it the hell away from life foods (dew worms r ok). I had no idea how dangerous goldfish were to oscars, they almost killed my poor baby (they gave her hole in head)
