Like, Im getting a tank that is 3 feet long and 3 feet wide by 4 and a half feet tall. It has a really wide footprint, but i dunno if I can fit a shark in their or not. Itll be sweet for puffers, lions and wrasses though. It may seem small, but that is 9 square feet at the bottom. Either that or im going for a 120 tall? Which would you think is better? Cuz the 130 IS custom, and it is nice...
