Zoas "gettin air"

[Kristy]

Different variations definitely have different sized discs... and no, not referring to palys, even just within zoas. There are some little zoas and some bigger fatter zoas. I've not experienced the stretching neck except for the occasional one positioned where it is reaching for light (like one that is down between rocks) while the rest of the colony is happy to keep their necks shorter.

A friend and I bought identical frags from the same seller. He looked at them in my tank and commented how much longer then necks are on his. I saw them in his tank and definitely agree. In my tank they are under MH light (same as the seller had them, just different wattage) and in his tank they are under PC lights. So that is consistent with what is being said here.

Which is what I figured Kristy. Great, then I am going to go ahead and move them up into a higher vantage point, adn see what happens. The one with the enlarged disk really used to be much more 'normal'-sized. I have no idea why it expanded. Perhaps rather than reach out, it just spread out to collect more light? We'll see.

I'll keep y'all posted.

Plus one for moving up. For the long necked ones that is. Mine do the same when they're in a shadow or too far from the light source.

I'd say you are lucky to have the larger one. Whether genetic or happenstance, bigger is always better.

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.

My aogs have long necks as well. I got them high.

When I hd pc's (lol) all mine had long necks, then when I got my new fixture (6 bulb t-5s) they all went down.

Long necks on my AOGs top of tank under MH. Newer AOGs have a shorter neck. When I frag, they are typically short for a while.

Bet you did Allan, bet you did.

All joking aside, from my experience, when corals stretch they need more light.

JMO.
