This is why I ask, it’s listed as a branching lepto. I can’t distinguish between the google images of a branching lepto and the ORA pavona, both are green with the very fine lines and what looks to be identical structure
Give it time, and proper parameters, it grows pretty fast.
Not the best pic, but I have a large colony of brittle star's living in mine, and thats what I was trying to get a picture of. You can see all the striped legs sticking out of the folds.
