yea this is amber (you might have met me in the breeding section) and I was wondering, how many rats do you think could fit in a 45 gallon tank? It is not actually a tank but it's like a shelf/dresser and it would have 3 stories to it. (each being as big as a 20 gallon tank).... I would have to cut holes in each level so they could get from one floor to the other. But just let me know how many rats you think would be comforatable in it!!! I will get some pictures of it up as soon as i can.. thank you!!!
