leather

Hi Everyone, I'm looking for some advice on my finger leather. When I got it, it had only 4 "fingers", and now there are more than 11. It seems to be growing so large that it's spreading open more like a flower than tall like a tree. Is that cause for concern? Do I need to frag it? I'm...

Based on this picture, can anyone tell me whether this is a nephthea or a green finger leather (sinularia)? You can't tell so much from this photo but it is a really cool neon green. I'll be fragging this up soon so let me know if you are interested! I've added a photo under daylights, too.
