I had one of those. Unfortunately while rearranging my tank one day, i damaged it pretty badly (don't ask)
I got a red Melon Sword to replace it.
I've seen some pics of HUGE Amazon Swords. That's kinda what i'm hoping for with mine. I've given it plenty of room to go so in time it will look better.
I also have a small unknown sword in my tank. I need to start searching what kind it is.
