The one I got from @t0mmy108 grew a new polyp in the 2.5 weeks since I've had it. Seems to grow about as fast as my other Zoas. I keep mine in lower PAR (~100) with a little bit of nutrients (2.5ppm NO3, 0.1ppm PO4).@t0mmy108 how fast is yours growing? Mine is still one polyp and it's been over a month
