This plant will sometimes develop those "rotting" leaves but given
moderate lighting, it will usually grow back from the small green tip.
Its usually not too demanding and should thrive in conditions where
other plants are growing. I think it does better in a slightly higher
nutrient fish tank with moderate lighting than a high light tank where
the water nutrients are low and the plants are getting theirs from the
substrate. Its a floater, eh?
