The sword is a red melon sword. Lighting is not too bad (around 1.5 watts
per gallon), I use the yeast and sugar setup for CO2 injection, fertiliser
tabs pushed into the substrate at the swords roots and also a trace element
mixture containing iron which is topped up at water changes.
My biggest worry is that the plant will need to attain a decent size before
it reproduces and if that's the case, I'll need to remove it before it takes
over the tank.
