Rock flower looking weird.

[Dorinda]

Ok, so I've had rock flowers for years. Nothing in the tank has changed. The green one on the sand has spawned a few times but no babies. I have 5 total.
Only thing different is I added reef roid because my phosphates were a little lower than I liked yesterday.

That looks like spawning. The bowl shape is typical in spawning, could be something else though

That's what I was thinking. Just haven't seen any action yet. 3 of the 5 are like that.
Thanks for the reply.
