A friend of mine offered me a free 120g yesterday but I had to decline because my mom does not want such a large tank in my 10'x 11' room, (the tank is 5' long) I have a 29g and two 10g at the moment that take up a lot of space. I am not employed right now since I am still in school and I am to young to work at most places, therefore my mom is worried it would cost a lot to get supplies and things and she would end up paying for the equipment. She says however that I may be able to convince her if I put together a compelling argument that includes the budget and equipment needed for this tank, this will also be a sort of "school project" as well. Please offer some advice! thanks!
