I can't say that my rtba is sick but it is loosing it's color. It eats like a pig and it still looks healthy but, over the course of a couple of months, has faded to a very, very pale pink. I have it rather high in my tank and I'm wondering if that has something to do with it. I have T5 HO
lighting. I tested my water last night and it is ok (except for CA
is a little low at 360).
I'm at work currently so I don't have close up picture but you can see it in this link. It's directly below the blue tuxedo urchin.
Do you think I should be concerned or just leave it alone?
