Bought it approx 1 year ago. It has turned brown and grown considerably,
but has not grown any new tentacles. As a result, it is huge but ony the
origanal tentacles. It still eats well and moves around the tank. Could
this be related to captivity? Any ideas?



Cnidarians that host algae will acquire the color of that algae. They are
clear or white...
As for the tentacles, it doesn't know its captive, if the need for new
tentacles arise they will grow new ones. Apparently your anemone's algae
have developed a diverse light spectrum affinity, thus the brown color.
The sole presence of color in your anemone reflects good health, maybe not
the one you like but there is no easy way to change the color. Try feeding
it with shrimp or colorful fish. It may work. Color enhancing food used in
its clown may also work, they will feed your anemone.
The color is not retained in the anemone's flesh but passed down to its
algae who uses it when synthesizing food, it may also rest in the algae's
tissue.
