Re: Rotala indica
> Are their colors supposed to be this variable?
Looking closely at my Rotala indica, I notice a lot of color variation on the
same plants. Some parts of the plant have reddish tops, others olive green,
others a pink hue. It's probably just the plant responding to specific
nutrients that existed in the tank when those particular leaves were formed.
Since I dose my iron and micronutrients about once a week, the iron levels
range from 0.25 mg/L down to 0.1 mg/L, at which time I add more iron and
micronutrients. I suspect I would get more uniform colors and shadings if I
dosed more frequently in smaller doses. However, I like the variety of color
I'm getting now, so see no particular need to change.

I don't think it's abnormal. My Rotala grows to a height of about 8" to 9"
(20-25 cm), and then droops over as you describe. It creates a thick mat of
Rotala, with growth winding in different directions. Again, I like this
effect, so don't worry about changing it. I think it's normal. Since you
have provided your email address, I'll send you some pictures of my Rotala,
as well as the other plants around it.
