Thanks, are you sure thats HM? Looks like rotala sp. green to me?? Looks better with the stems
It could very well be a rotala, as the leaves are a little largish for HM, but HM is what Saintly's been saying, so it is convenient to say. Saintly, why don't you post a close-up of the background stem so we can be sure? It is also not growing like HM, not nearly dense enough, considering the amount of light you have. If you really had HM, it would be very compact like it's cousin, HC. It is however, difficult to judge scale in these small tanks.
