Lower light Zoas or Paly's?

Discussion in 'Coral' started by Bruce Spiegelman, Feb 22, 2017.

  1. I have a large shelf rock where I'm currently growing out a zoa garden. Above it is a rock that has some zoas growing nicely down a gradual sloping front. I'd like to find a zoa or two that I can spread down the side as well, but it receives somewhat shaded lights. Any thoughts of what might work? Or is it just hit or miss with every colony being different regardless of type or species?

    I noticed that when growing on slope/shaded, zoa tend to get a lot more spaced out. What about making it a mushroom slope?
  3. I'm not big on mushrooms, plus I love the look of dozens of different color Zoas all growing together and overlapping.

    In lower light the stalks become elongated, like they're looking for light.

    Purely anedoctal and from my small sample size of frag plugs in lower light, but smaller polyp zoas like rastas and eagle eyes seem to do okay. And like @Gablami said, my larger polyp zoas will stretch their stalks to reach the light even though they're at the same light level as the smaller zoas.

    Low light for me at max light cycle though is still at least 80 par.

    Most of my zoas are on the sandbed where the light isn't very high. They're getting like 70-100 on the PAR meter last time that I checked. No elongation on any of the stalks.

    Rastas, PPEs, utter chaos, and some sort of vampire zoas in the background.

    I the majority should be fine. I have had problems with zoas getting too much light but not really vice versa. I have some purple deaths and grandis in particularly shaded areas.

    I second @RandyC on eagle eyes surviving OK in shade. But zoas are much better in light. This colony is under an overhang but occasionally one side gets a little light reflected on it. You can see how they brown out and get smaller and more stretchy further into the shade. [​IMG]
