The sword is healthy, and that is E. bleherae as it is generally labeled. With two tubes now this should get larger, provided you dose Flourish Comp once or twice weekly and put one Flourish Tab close to the roots and replace this every 3 months.
Only thing I didn't ask was the GH. I don't see signs of calcium deficiency, but it would help to know the GH of the tap water. Swords are heavy feeders, and calcium is an essential macro-nutrient for cell development.
I would expect the plant to grow taller under the afore-mentioned regime. It can take a few months for this to kick in after changes. I have had these plants for years, and even in the same tank they go through periods of increased growth and then level off for a few months. Plus there is considerable variance in the growth within this species. As I have commented recently ion a couple of other threads, it now appears that botanically-speaking the species we have known for years as E. bleherae, E. amazonicus, E. parviflorus and E. grisebachii are not distinct species but one and the same. DNA studies have proven this. So when one considers that E. amazonicus grows much smaller than E. bleherae, and E. parviflorus is much different in leaf shape from E. bleherae, it should not be surprising that we get different growth formations from the same plant, nor that the same plant can vary so significantly according to conditions.
