The problem with rock wool is that fish sometimes try to eat it, and it can kill them.

Also it can get tangled in a filter intake and clog/break the impeller.

I had my brazilian sword (or atleast it what it was named when i bought it) for several months and it grew quiet fast, its leaves looked my amazon sword but they were wider and had thicker stems. then all of a sudden all the leaves started growing really long stems and grew out of the water, now i have 5 stems coming directly out of the substrate that are squeezing through the lid and have thick green leaves. the plant looks great and it looks awesome having some leaves under water and some above water. i have a 29 gallon so some of the stalks are >20 inches.

Spath, often sold as "Brazil Sword" is not aquatic. It does, however do very well as a water rooted plant. I have used them, very successfuly, as filter plants. If they were grown in soil you must cut off all the soil roots and put the stem in water. The stem will then grow water roots (a different type of root) and live happily with the roots sumberged indefinitely. I don't know how long they can survive with every leaf completely underwater from my own experience, thogh people say several months to half a yeear. They will definitely try to break the surface before they die.
