Okay so I used to think that long necks meant starving for light but im not too sure that is always the case. I have about 15 different colored zoas and palys and all of them are colorful and healthy. I use 2 250w MH bulbs for lighting and pretty much all of these little softies are low in my tank. There is 1 colony though that no matter where i put it in my tank it seems to be reaching for light and thats my AOGs. They have always has long stalks and I dont think they will ever form in a tight group. I think this particular morph just has long stalks but I could be wrong. I have had these for at least 5 or 6 months.
