Let me tell you that you may even find yourself getting an even bigger tank down the road. When I got my first oscar about three years ago I actually wasn't planning on getting him or such a big tank. But when I saw him in the pet store and found out that his first owner gave him to the pet store because the owner moved I went from looking at buying a 25 gallon tank to special ordering a 105 gallon tank.
i've decided...this site causes mts!!!! you read about all the great things you could do if only you had one more tank....if only your tank was bigger...and before you know it....mts has taken hold of you! its not got me yet, but that only cos cant afford to yet! been window shopping though!!
