yes, herein lies the ultimate problem that is especially prolific in the zoanthid forums. When we name something, we are simply placing a name on a color, NOT a specific coral. It makes generalizations like I made rather useless unless you have the same version of RPE that I have. Yours is probably a different coral that LOOKS the same and we call them RPE assuming they're the same.
Of course, we also are not discussing absolutes- like water parameters and light spectrum, but just discussing relatives. What is "high light" for one is not for another.
These things make discussion of color maintenance and acquistition quite frustrating!
It is interesting to know yours act differently than mine, and all the info exchange is often usefull, but certainly difficult to draw much conclusion from!
Cheers!
