could be due to many reasons.

best to provide a pic for us to see what kind of zoas it is before i could comment more.

but one major issue with brown is light, most occasions in my experience are due to intensity and spectrum difference from where its harvested.

that being said, its pretty hard to solve that issue especially on spectrum problem.

If a man could beat his own fantasy. Then to only breed in captivity. Then its pointless.

Genesis 1:20

And God said, Let the waters bring forth abundantly the moving creature that has life, and fowl that may fly above the earth in the open firmament of heaven. And God created great whales, and every living creature that moves, which the waters brought forth abundantly, after their kind, and every winged fowl after his kind: and God saw that it was good. And God blessed them, saying, Be fruitful, and multiply, and fill the waters in the seas, and let fowl multiply in the earth. And the evening and the morning were the fifth day.

Hi EngSeng,

Zoas in a way is a little like sps interms of the lighting and colour relationship.

Generally speaking, higher the intensity (assuming right spectrum), the brighter and intense of the zoas colour. But nutrient level could also affect the colouration, i.e. higher the nutrient, the chances of it getting brown is also higher.

So in the worst case senario where the tank is having high nutrient + low light intensity you will get very brown colour. Tweaking the nutrient level and light intensity will give you a corresponding result. So to get a very bright nicely colour zoas, your best bet would be a low nutrient water and higher light intensity.

Give it a try.

Treat others the way you wanna be treated...

Attached are some zoas photo...

Law,

the dragon eye at IMG_0848 is I get from u last time...remember e skirting was lime green and center more orange...

I changed my lighting tube 3 months ago...

I read online that the guideline for lighting is minimum 3W per gallons...i only using T5, 4x39W for my 3x2x2 ...

so i suspect my lighting is not sufficient...what do u guys think?

:ThanxSmiley:

you can try shifting them higher.
