Got a dumb question....I just bought a tank from a lady. She says it is 55 gallon, but it is really big - I am guessing 4' x 1 1/2' x 2 1/2' or something like that. I haven't picked it up yet, so I can't measure it. Can anyone tell me what the measurements are of tanks or how to get the correct gallon size of one?
