Do you think this brown patch it's a lack of light.I have 5 overdrive 24w t5ho over 29 gallon.The brown patch growing a little since 1 month.All parameter is ok.

Did it look like that before? Some clams have patches of "yellow/gold".

my crocea looks like that.....it's a natural color......nice BTW

I have order my crocea on internet, i don't know if the brown patch was there before shipping.But i know the brown patch growing little by little since i have them.

It is possible for the colors to change to adapt to your lighting.

I have a squamosa that I purchased that was mostly black and white when I got it. Now it is getting more of a golden brown tone to it.

it's fine.....i wouldn't worry about it


this is my crocea
