Seems similar, though its at most 1 1/2" across. Guessing it needs more light than i have (nearly 2w/g) I dose with flourish, excel, iron and trace regularly. I like the red accent it gives the tank.
Any other suggestions for what it is? If it was the myro i would expect denser leave growth seeing it has the colours of being grown in ideal conditions.
i bought them as stems there were a few starts of roots. But i thought id just let them settle in and establish before finalising the placement. Thinking i may get more of them or something similar as the left hand side is real empty but that is the shallowest substrate area
