Thanks Jen. Fresh, you might find this amusing;
while you graciously gave me a Micranthemum umbrosum stem,
the Bacopa monnieri was actually a hitchhiker buried in the
Elatine triandra you sold me. a week after planting your ET
one lonely stem started growing vertical instead of Horizontal,
and with extra care I nursed it into that lovely bunch of BM
you see today

what I love most about BM is how it does
not seem to attract diatoms on it's lower leaves like MU does.
BM is so soft that my fish seem to like swimming thru it, but
it does not break apart into floaters as many fine plants will.
I like this BM much more than Hemianthus micranthemoides.
amazing what hitchhikers you can get plant trading.
recently I traded for a baseball of Glossostigma elatinoides.
I isolated the plants in a container for a few weeks,
(I'm paranoid about getting other peoples algae)
and found;
duckweed
java moss
black ramshorns
even live Daphnia!
