That gaudy looking red weed?
Ludwigia pantanal.
There's (from L-> R)
Eriocaulon secetum
Tonia fluviatilis
Ludwigia pantanal
Tonia sp. "belem"
Ludwigia "cuba"
I have Rotala wallichi in here and other Eriocaulon's and a rug of HC.
I had a nice Ohko stone scape in here, but am tossing them out and going Dutch row in the arrangement.
I just got the pantanal and the Tonia "belem"
Last week and have over an inch of growth already, the L pantanal is a very nice plant.
Tonuia belem is much easier to grow than the T. fluvitalis which I get 2" a week out of and have 15 new 2-3" stems from last week. The issue is raising the new stems, they need more light than I can give them in the layout I want, so it's not much of a nursery tank.
Sopme plants are tolerant of that, but if these plants are shaded on the sides, they tend not to do as well.
The L. pantanal looked pretty sad looking and has in stores also, but it's really liven up well at home. It does well with fast growers also.
These plants do prefer soft water, but I've not found anything to substrate they require acid conditions, nor low pH's, nor ADA substrates. I've grown the hardest of these in plain old flourite.
I also got 2" a week out of the Tonia fluviatilis, but the water had a low KH, 1-3 degrees etc.
That seems to be the only real requirement.
ADA soil will certainly help though, and it's good for root growth vs flourite for the Tonia fluviatilis, but stem/leaf growth was the same. You can see visibly more roots on the Tonia with ADA soils. Most likely do to soft nature and NH4 content rather the acidic nature(we can add peat if we want to explore that issue), and you can add soil for macro's like NH4 etc.
But for most, simply getting the ADA soil does make things easier.
I'm not impressed with the powersand though. It makes a mess when you replant/uproot.
The other large factor was switching to CO2 mist, although I did well with these species in FL + flourite without CO2 mist.
The mist really causes the growth spurts to increase in ther Tonia and leaf cone size diameter increases nearly 2 fold, a very marked difference.
This tank is simple EI dosing and CO2 mist, 8800K lights from hellolights(5.5 w/gal). There are 50 cardinals in here and 50 manao shrimp, and a few Royal Farowella babies.
