questions for the zoa experts

[Wheelman76]

I've had a few zoas out of a colony do the umbrella thing , but they were on the sandbed in a 24" tank with T5 lighting , they always went back to their regular shape and never showed any negative effects from it.

The god of wars are also essentially on the sandbed in a 24" tank. light is a mitras. the redds are about 8" off the bottom.

i have increased the white spectrum not sure that's worth noting.

No I'd say just the car ZOA's and palys moph when placed some where they don't like the most common thing that makes them morph is light I think that's what's happening to your candy apple reds

Also my ZOA's will do the in blella thing when the salinity is to high but normally not just a select few do

[reefwars]

unbrella syndrone is linked to nitrates not lighting

its most common in PE's but all zoas an do it


theres a very good thread on RC about it and how nitrates effect it

for what its worth there are very few zoas that need low light like very few , in fact most can acclimated and do best in high light.

thanks guys. i'll give my nitrates a measure before my water change and see if that's high.

just to shed a little more light on the matter:

nitrates are near undetectable and my phosphates are apparently around 0.01.
