I'll get down to it. 30 gallon long (what I want) 30 dollars and i gotta drive an hour and a half each way to get it. 30 gallon tall. 10 bucks, across the street. well actually its like the 29 or w/e its not the 30 extra tall. the tall is 30 inches long and the 30 long is 36 inches long. i think the tall is 2 inches taller. Is it really worth it for the extra length and 2 inches of shallowness for added lighting to get the long? it will have a 55 watt pc light and a NO flourescent. thanks lots guys. Please reply quickly.
