the "rubin" is the shorter, large-leafed red/pinkish plant and "red" is the to the left.
med/high light, co2 and consistent fert dosing.
a closer look at the 'rubin'
Keeping the 'red' as red as it is has never been an issue for me... but the 'rubin' on the other hand, this is as red as I can get it. the underside of the leaves are a deep red, but the tops are what you see... any ideas? and my ludwigia arcuata will only get to an orange/rust color
very small leaves, definitely a sign of no co2.. ludwigia repens leaves are about the size of a quarter when receiving all required nutrientsI have found that the more light the redder the leaves and the leaves that do not get that much light stay greenish.
This is ludwiga repens (think that is what it is called) in 29 gallon high with two full length 6500k flourescent bulbs.
It grew like weeds with no co2 just 2 gallon weekly water change.
There is some jave fern here and there.
