much better indeed. width is always important and the main deciding factor in what can go into the tank. if you want interesting fish or monsters you can go in for piranhas. tank this size would look great as a sunken forest as well. drift wood is much lighter than rocks. or you can keep medium sized monsters such as lima shovelnose cats, black knifefish (very interesting to watch kinda like a mini clown knife) and bichirs like ornate, senegals. florida gars grow slower than aros but are much cooler to keep.
