yellow star polyp questions

I have a small colony of these. They eventually grew out from about 4 polyps to about 10 and are now back down to 5.


Do these require high light?

I've been keeping them on a small rock on the substrate of my 55 with T5's bc I'm hesitant to let them get a hold on my main structure... but if they continue to grow slower than my LPS it may not be an issue...


I've moved them around to different flow but they don't seem to care. I haven't yet tried high light...

thx reefers

 

I think your light is OK, mine seem to do best when water quality is high. I do keep them at mid level in the tank so that may be the final piece of the puzzle for you.

 

I have kept mine at the bottom of my 40b with moderate flow and they seem to be very happy.
