Anyone know what plant this is? Not the Rotala or Elatine but the stuff around the center rotala.

The stuff around the Rotala macrandra "Green" stem? Why, that's my Hedyotis sp. Rio! :D

I sent some to Jim earlier this year, and I know he has been spreading it around as Rotala sp. 'Pointy' in SFBAAPS.

Thanks Carlos! Not to much information on line, any info about this plant? What is your experience with it? Looks like a nice small plant. I like miniature plants because I work with small mediums (20 gallons).

Nothing is available online.

Your among the first dozen or so people to have ever grown it for aquarium usage. I first got it as a gift from a hobbyist in Brazil, who gave it to me emersed. They had not tried it in submersed culture when I gave it to them. They actually thought it was a Rotala species, but I eventually figured out that it was actually an aquatic Hedyotis -- don't know the species yet.

I found it extremely easy to grow and actually a little obnoxious, as it has a tendency to shed growing tips which settle elsewhere in the aquarium and grow new plants. Seems to like CO2 and lots of traces/PO4.

There is actually another plant I gave to Jim that is a Rotala, but from the same place the Hedyotis was collected. This one has bright red stems emersed. Submersed, it looks identical to Rotala "Green" save for its tendency to carpet the substrate -- it seems to be a new foreground option.

Have fun with it,

Carlos

Wow, thats neat. Jim is great. If you ever wanted to spread a plant throughout the US, he is the one to give the starter batch to. He got me into making the HC emersed setup. I'm thinking of transforming my old 45 gallon in the garage into a plant farm for these new species. All I need to get is the 4 x 55w kits from ahsupply. I've got a little pump that I was going to put at one end of the tank to pump fertilizer through the shallow watered substrate. The HC has exploded in the small emersed setup I made a couple of weeks ago.
Thanks,
greg

Hedyotis sp. 'Rio de Janeiro Botanic Gardens' #2 is a really cute "weedy" plant. It is by no means "miniature". Under high light setups, it will quickly gain heigth and produce an abundance of side shoots with long internodes; though it will stay as small as your diligence in pruning. :wink: Albeit a beautiful stem plant that tolerates low light and no supplemental CO2, it has a few quirks:

(1) It roots poorly, but is much better at staying anchored than Micranthemum umbrosum.
(2) It has very delicate stems that snap easily. Growing tips often get broken by fish brushing passed and colonize other areas of the aquarium.

Of course, a post isn't complete without pictures :mrgreen: so here are some from Carlos' tank:
