LOL number one thats not a big a s s aquarium..... it looks like a fifty five gallon, it might be a 75 (thats what i have) they are the same except the 75 is deeper.. just so that you know if you dont have any stuff with it then you will probly only get like 50 bux for it, my buddy at work is selling one with stand/filters/light for 100 bux..
BTW if your wondering yes im a fish nerd...... i have a saltwater reef tank in a 75 gallon that ive had for about 9 months.
fishtanks are a b i t c h.... and they are very expensive. i have about 2200 dollars into my reef tank.

or you could just get a freshwater tank and put some cichlids in it

cheap and pretty sweet fish!
