|  Questions About Zoa's
I've been noticing that most of my zoas are not as colorful as before. I have some brown with green in the middle, now its only brown. Lite brown with orange in the middle and now only brown. My other ones are still the same colors but not as opened as before. I have checked my parameters and everything checks out. The only factors that come to mind is my skimmer is working too good or my lights need replacing. My lights were replaced on 07.15.07, both MH and actinics. Has anyone had the same problem? _________ 9YR OLD 90G 30G w/d Mag18 150G skimmer 692w MH,yel&kole tang,foxface,midas&convict blenny,B&G chromies,Blk/yel fin chromie blackcap,nemo,neon goby,6line; Blastomussa Merleti,Acan ,BUBBLE,Torch,LTA, Goniopora(2), Acropora(2),Brain, Moon, assort zoas, yel& G star polyps, R&G open brain, P&B ricordia, montiporas, cup&candy corals, enias,B/G mush,flower ane(2), cherry red mussa, dusters,cleaning crew  |

Hey Lunatik, was it a gradual change or did the coloration change over a period of time? I am thinking that if it was over a period of time it might be the lights? Also, mine tend to like a lot of flow....  _________ 72 gallon bowed 150lbs LR 60 lbs LS

Your lights are not intense enough for them to maintain color. The bright colors you see in them are their defense against intense UV rays. Zoa's need high light, high flow and a lil dirty water to thrive. _________ Got Questions? Need Answers?

As you know, I obtained my zoo's about 24 hours ago, and so far they're doing very well! (Which is kinda like saying my 3 week old truck looks great!! LOL But as the weeks go by I'll stop by this thread and keep you updated. I got a good photo showing their color. I'll post another in a week or two. I have 5-T5s atop my 55 gal.

Hey Lunatik,
Try moving your zoas further up in your tank. How high is your tank? I do agree that it is probably the lights..But, one important things that a lot of people don't realize is that they like a lot of flow... | |
