Re: A true SPS...
Sorry Heinz... you are wrong. Algae do not have polyps.
The SPS in question is covered in small yellow polyps. I will try to get a MACRO MACRO photo for you all to gaze upon. Larger pics are in my gallery.
Branches are the size of needles. Polyps retract when small hermits and snails crawl on top of it.
Growth rate has been from a single dot to current size (appox 4" across) in 9 months. Saw first branch about 1 month after the rock went in.
Other outcroppings on other rocks have not gone beyond a single branch (1/4 - 1/2")
Can anyone identify this SPS?
