banana plants are great

. if they're cheap, try buy a couple and put it in a seperate container from your fish. they usually *re-live*

they're really easy to reproduce too. i have two of them
one of my banana plant, i thought was dead and it was in a large cup, and said, what the heck, and plop it into the tank, now, it's doing better than the one that was originally in the tank
try to get it, they're really nice and cool, ...... and hardy!
*look* at this below
