I wonder if it really is Horemani. In my experience, Horemani
quickly smother even a 24" deep tank in leaves. I've measured the
_leaves_ at over 40". Could it be a 'Rubin'? This is similar in
looks to a red Horemani, but stays considerably shorter... Mine

No, they don't grow anywhere _near_ as fast as Aponogeton flowers,
and last _much_ longer.

Very few (if any) Echinodorus sp. are self fertile... you'll need
another plant flowering at the same time to produce seed. Even if
it's a different species, you an produce some very interesting
hybrids (like the 'Rubin') by crossing Echinodorus sp.
Regardless of whether you get seed or not, you will probably get
plantlets. Echinodorus sp. produce baby plants on their flower
stalks, particularly if the flower stalk is kept below the surface
of the water. When these plantlets have gained a little size,
they can be removed and planted separately in the aquarium.
If you _can_ fertilize your flowers, and you get seed, start them
by placing the seed on a fertile (soil) substrate that is pretty
well soaked, but not submerged in a closed aquarium to retain
humidity. They will need either good strong artificial light, or
a long period of indirect sun light each day. You don't want a
sunny (usually south or west) window, as the closed tank will heat
up way too much. Try a north or east facing window.
I don't think you'll get the seed to germinate in a standard
aquarium set-up. Aponos will do this because they are fully
aquatic. Echinodorus have several reproductive strategies because
they grow submerged, seasonally emergent, and sometimes in
permanently bog-like conditions.

I just had an article on Anubias come out in the November issue of
Aquarium Fish Magazine. If you can't get this magazine in
Austrailia, let me know. I can't send you the photos, but I can
certainly send you the text.

I think this depends on the sponge and the particular canister
filter. Both can be good biological filters, but I agree that's
not a crucial function in a planted tank.
> o They're a damn sight easier to clean
I don't know... I hate pulling a mucky sponge out of the tank
while I drip dirty water all over the place. I can disconnect my
canisters and carry them to the sink for cleaning. The whole
process takes no more than 5 minutes per filter.

You can see through the colored but transparent plastic of my
canisters with no problem... And I don't have to look at them
inside my tank. (or plant around them either)

Besides my comments above, Canister filters are much better at
mechanical filtration than sponge filters, and that, IMO, is the
main function of a filter in a planted tank.
