Cute-cute-cute! (was: Submergent/emergent)

I think the emergent form develops from the point where it breaks the
water's surface. I'm not sure what happens with the submersed portion,
though - whether it proceeds to rot away or stays good...

I saw this very set-up yesterday (without those plants, of course) at my
LFS, only it also had the cutest little teeny-tiny power filter!!! An
ACTUAL power filter that hung off the rim! And it even had adjustable flow!
Oh, my gosh, it was SO cute, but I would have had to buy a whole set-up and
I didn't really care for the 1/2-gallon "tank." I guess it would have been
worth it for the CF light and power filter. I was amazed that the filter
flow was so perfect - nothing was "blowing around" in the little cube. Even
at high flow rate, it wasn't absurdly turbulent. I'm sure I'll break down
and buy the whole thing at some point in the near future. Cute-cute-CUTE!!!
Why not try some teeny-tiny plants for your teeny-tiny tank? Or at least
some slow-growers? Right now, I'm growing Lysimachia nummularia 'aurea' in
my 2.5-gallon tank. I know Tropica says it's a fast-grower, but I'm finding
the contrary to be true... But it's hardy and has beautiful golden color.
I've got dwarf hairgrass growing very slowly but steadily for me. I bought
something yesterday called Rotala sp. 'Nanjenshan," which has the fluffy,
needle-y look of a Myriophyllum. From what I've read, the only real
"demand" it has is strong lighting, which your 7-watt CF should provide,
and it's supposed to be a good choice for small tanks. Bacopa monnieri is
okay, but may grow quite rapidly under those conditions. Finally, if you
can get your hands on an Anubias nana 'petite', that would be SO perfect
for a teeny-tiny tank. I'd also suggest pearl grass and baby tears, but for
the life of me, I can't get the former to grow, and the latter grows too
fast. All of the plants you mention are ones that I'd think would quickly
outgrow a 10-gallon... Just the tuber of the A. crispus would practically
make the water overflow in a palm aquarium ;-). But I guess the cube would
make a good nursery, if you intend to move the plants to a larger tank, soon.
Happy teeny-tiny-cute planting!!! :-)
