Personally, I can't say with much conviction that it looks anything like an Alismataceid (the family that includes Echinodorus and Sagittaria).
The pellucid lines (milk tubes) on the leaf margins, as well as the darker coloration of the outer margins, suggest to me a Vallisneria species.
How much light do you have? I have had Vals grow like that under higher light.
A good way to determine if it is Sagittaria or not is to look at the tips of the leaves and the roots. The leaf apexes (tips) in Vallisneria are usually toothed, and V. spp. have fine roots. Sagittaria have larger coarse ones and are always untoothed.
