red hue

Another sign of improving health- my rotala in the aquarium has a new shoot that is reddish. Hard to photograph, but it's here on the upper far left,

and here in the center:

This plant tends to have reddish foliage on the upper part of stems, I've seen photos of that but mine never did. I also see some back-and-forth online about what can encourage this. Lots of people think if you provide more iron, the leaves will turn red, others say that's not so- it's just stronger light and better nutrition. I'm just glad to see it.
