Swords are root feeders and like Iron. Root tabs under mine and lots of new growth. I got one recently at half price so I picked it up.
Thanks for this info, I am using standard API root tabs at the moment, which mention no iron or any of the important trace amounts to be honest, so I have just put some on order which contain trace (potassium and iron and all the rest I cant think of) along with the normal contents. Right now I am using a few flourish products to ensure they are getting at least some of what they need. I got a sickly looking java fern from the aquarium too (also free) plucked out most of it's leave and attached to bog wood, hard to believe the plant on my wood now is the same. They buried half the plant in gravel and were killing it.
When I started my aquarium it was never meant to be planted but I couldn't bare seeing the plants they had dieing, so one day asked if I could take one home with me, now I've had between 30 and 40 plants pace through my aquarium. 5 of them died never to be seen again and the rest survived themselves or through seedlings or new growth. so now I think I am a bit of a green thumb
