I went to the LFS for my fix, today
. I saw a very pretty plant simply labelled "Ludwigia sp. NEW." Despite my terrible skill at growing Ludwigias of any kind, I thought I'd give these a try since they were so pretty, healthy, and relatively inexpensive. They're in my new tank.
I have a feeling that they're L. sp. 'Pantanal' but I can't be sure since I've never actually seen the plant with my own eyes. So could somebody please confirm if they are or aren't? They're in the album labelled "???"
Sorry the shots are crummy. The leaves of the plant sort of got crumpled on the way home. For the top-view photo, I had to move the strip light to the side, which ended up making it look washed-out.
Anyway, will they be okay in an unheated tank? It doesn't get too cold in the house. There's some granular peat under the Flourite to hopefully bring down the pH. At the moment, I'm only adding Excel but will probably start dosing fertilizers next week.
Thanks for any help with ID and care.
