ok guys i need some help here 
first things first i stay in an apartment on the 4th floor
i am going to boarding college by 1st week of july so my parents forced me to give away all my birds
....this caused my balcony to look empty so i cleaned it up and put up my old 18inch*1ft*1ft tank on my balconynow i am not a person who can stand an empty tank
so i want some suggestions as to what i should put in the tank for one month
