OP you need to list tank parameters, what lights you're using and for how many hours a day. How old is the tank, how long have you had the palys.. that sort of information if you want people to actually help.

Ph.8.4 Alk.7 cal.420 Nicrew blue did great at the start. 12 hours a day. Tank is 6 months. I have had the Palys for one week now.

Well I don't have a picture. But I'm pretty sure I know what your talking about. I have some slow grower bright blue zoanthids that have these small light brown triangles on them. I do not know the cause as the other zoanthids are normal and fast growers. Potentially just genetics? Or maybe just coloration.

Just a color-morph thing probably. I know some Palythoa's polyps have a single white stripe on their dorsal mesentery, so this is not too far-off.
