HybridHerp I'm getting some Rubin in a few days, and I already have red, so I will try and compare once the rubin settles in as well.

vqfive I have both Rubin and Red. The Red I purchased looks like a mini Rubin but is always red color from top to bottom

It is very similar in shape so is entirely believeable
palustris seems a bit mroe elongated in leaf form.
i woulnd't mind setting up a comparison grown under the same conditions if i could get my hands on some

Try replanting 6 inches or more of stem as this gives the plants more nutrient store. as it grows in and matures in ur tank, future replants will be less stressfull

HD Blazingwolf here are two shots of it

the yellowish red repens is with low co2, low nitrate, low phosphate frm when i got first started

the bigger leafed bubbly ludiwiga is not red becuase i have it far away from the lights, but it has less co2 deficiency.. the curved leaf is still a good co2 deficiency sign

Thank you very much, it grows great but what you have said about the leaves being quarter size with co2 makes sense because I see this plant growing by canals (that is where I got it) and the leaves on those are quarter size while mine are nickel size if even that.

I just assumed since it grew so fast that water changes were enough.

I have a second corckscrew val tank recently set up and was thinking of DIY CO2 , will try it in both tanks.

The water here is the best for no algae at all and amazing plant growth but as you know doesn't come with CO2 so going to try it with soda bottle and air stone in tank.

HybridHerp while on the topic, I feel like sp. atlantis should also be discussed with these two
sure, price wise there is a big difference now, but appearance wise and size wise and all I think these three sp. are very similar.

HD Blazingwolf the orange leaves in this picture indicate less than optimal light for the plant (ludwigia red)

orange is a common under leaf color for broader leaved ludwigia species

Monster Fish

Ludwigia sp. 'Red' on the left, Ludwigia 'Rubin' on the right. The Red took about 2 weeks to turn that color while the Rubin has only been in the tank for 2 weeks and only has orange under the leaves. It's still growing though, about an inch every few days. The tank has DIY CO2 and daily Metricide-14 dosing, EI dosing, and MGOCPM capped with Seachem Black Sand. The light is a 27 watt daylight desk lamp positioned 3 inches above the water timed for 6 hours with a 4 hour blackout then back on for another 5.

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.

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

The Rubin is very pretty looks like a flower
