I have just recently made the leap into raising live plants. I now have
about a dozen cuttings of "hornwort" (_Ceratophyllum_demersum_). The *.aquaria
plant FAQ described hornwort as a floating plant. However, my cuttings--which
I've had for ~1 week--are sending down some white shoots from their bases. I'm
assuming these are roots. So, I'm wondering: is hornwort indeed a floating
plant? Perhaps it is a floating plant that prefers to be anchored to
something?! Anyway, I have placed 7 of them onto a large piece of "lava rock"
in my tank. I figure they can anchor onto it if they care to. Some of the
others are still free-floating. Some others are near a ledge that I have for
the fire-bellied newts in my tank.
I plan to get a few good books and also observe the plants' reactions to
their relative placements. In the meantime, can anyone tell me what is exactly
going on with these pseudo-floating hornworts?
