They're very sharp. I've seen that strain before in a zoa garden shot by another zoa collector. Alas, I can't find the screen shot but I believe they were called yellow submarines, google search is showing ones with different colored lashes.
Yeah its just that theres no yellow in these. The disk is a light green and the skirt is a green also and the center is blue. I'm going to call them Gaia and call it a day lol
