I have zoa colony of white-lavender color, marbled appearance. In my low tech low light tank it become eventually solid dark violet with orange center, similar to My Clementine. Grows well, too well, no stretching or contacting because of light, and this is a low nutrients tank, dosing them.
What could be a cause of it and can it be corrected?
