No, those are not the red royal farowellas, those only get maybe 3-4" max, these are Sturisoma arueum, they get 10-12 inches.
What is odd, I've never seen this size breed. Maybe 5" or so?
Plants in the background:
Hydrothrix, Red Pantanal, Erio type 3(a few type 1 in recovery), and 3 different types of Ammannia.
Nesaea crassilus is in the mix also.
The Ammannia is suppose to be senegalensis, but it's huge.
As in the same size as gracilius. I have A gracilius that looks normal, then a red stem slow growing form of A gracilius that was sold to me.
It's a slower growing and more deep red type.
I'm not sure it's the same species or just a different variety type.
There's another A. senegalensis which I do not have and I've seen a different version a long tiem ago also, sort of an olive colored one.
What I know to be A. senegalensis is red/orange and about 1/2 the leaf length as A gracilius. That is what was supplied to the hobby for several years, 1-2 decades.
These new deeper red types which grow slow are nice though. Harder to grow, but nice because they do grow slower.
The lower growing stuff on the far right is Ludwigia pilosa. I sold most of it and then saved the stumps which regrew nice tops again.
Nice plant as well.
