Glad to hear the DHG is working for you. I've just planted some in a nano myself and am looking forward to it doing well. When I first got into planted tanks I thought grassy/mossy plants were boring and I avoided them. Through my experiences, I am beginning to love these simple, soft-looking little guys and stems and broad-leafed plants are beginning to take a back seat in my mind.
I'm waiting for some mini moss I orderd to arrive, so the both of us may be trying to tie the stuff on at the same time. This will be my first time trying it. I'm wondering what the tricks are to making it look natural. Guess time will tell.
I'm waiting to be able to take out my floaters, too!
Good luck with your nano. They're a lot of fun. I'm actually starting to prefer smaller tanks over larger ones. They seems to be easier for me to wrap my brain around and I think they come out with stronger layouts because I don't end up getting distracted a long distance away from the centerpiece. Maybe I'm just inexperienced.
Ottos seem to get maybe 1.75" and I hope yours are more entertaining than mine have been.
Seems like it hard to beat using wood, grassy plants and moss for something simple, elegant and peaceful.
