    Darn. I have to wait till Juggler trims his HM

    Thanks for the ID, and the note about the emersed leaves. They grew to the tip of the water surface today

    It appears that this is an emersed form, correct?

    Is the submerse form of rotalas having thin,long and yellow-greenish leaves?

    Depends on which Rotala rotundifolia variety you are referring too...
    There is the Green variety and also the red variety... Red variety gives you reddish-yellowish-green leaves when submersed...

    Green variety, of course gives you green only... If yellowish, means dying?

    I got a big bunch of emersed form from Teo. It was greenish looking though at the time of purchase. However after almost 1 month, the submersed leaves grown out to be yellow-greenish in color and the stems are long and thin too.

    I was having like 1.2wpg at this time, so it could have been that the insufficient light caused this "deficiency".

    Anyway, I just changed to a DIY 2x39W T5HO, and saw these rotalas bubbling for the 1st time in my tank.

    It is difficult to tell a red variety and green variety from the emersed form... I for one, can't.. Some guys are able... So yours probably is the red variety..

    Insufficient lighting might cause the stems to be thin and long as they grow up quickly for the light at the top...

    I think what Terence have is the green variety. My reddish ones have a slight flush of red on the stems even under low lighting (1.5W/gal). In the pic, you can also see the emersed leaves in the background, top left hand corner. The leaves are round, hence 'rotundifolia' (rotund=fat round). It certainly perplexed me when I first came across its scientific name, as the submersed leaves are anything but 'rotund'. It wasn't until it grew out of the waterline in my open top that I understood the rationale for the name.
    Regards

    Oh and yes, I read somewhere that if you blast it with intense sunlight, it will start to creep rather than growing upwards, unlike the other varieties. Just look at some of Amano's tanks, he lets them cascade over rocks. So swee! I wish I could get my hands on some. Only have this orangy variety (not red) from Australia, would love to try the green and red ones.

    Seems like I have a long way to go in identifying stemmed plants... I thought the Bacopa was Micranthemum umbrosum

    Thanks guys!
