Hey all, a couple of my zoas used to have rather large heads, and they had long stalks. Specifically my Red People Eaters and my Illuminatis.
I always thought they wanted more light - stretching with any photosynthetic organisms seems to point to this conclusion. I added a 2nd AI Prime over my 24x19" footprint tank. Since then, the heads on both have shrunk down by about 40%, and they now have no visible stalks. Instead, they form a very tight mat.
My question is whether or not I should see this as an improvement or a warning sign. To me, they actually look much nicer now, but they are getting very high levels of par (est. 250ish). The colours are very vibrant otherwise. They haven't put out a new polyp in a couple weeks, since updating the lighting situation, but I also don't want to keep moving them around too often.
