I think it is hilarious, but I have heard nothing but bad news about the living conditions. With the equipment added it, it's less than a gallon I believe and the decor (like the plant) is quite sharp.
There was one customer who mentioned that he simply took all the decor out and plunked it into a larger tank. Hey-- for only 13 bucks (plus the price of a 2.5 from Petco) why not?!
