Editorial: August 2005

About two weeks ago I had to make a draconian decision. For
several years I had a small colony of the Majano sp.
anemones in my 10-foot reef tank. The colony survived next to my
Euphyllia ancora, because the old tomato clown (A.
frenatus), now in its 23 year in captivity with me, trying
to protect his/her home from my Navarchus inadvertently
also protected the Majano colony. Everywhere else in the
tank the Navarchus ate the Majanos. However,
several months ago for reasons only known to the angelfish it
stopped eating them. Quite quickly they started popping up all
over the tank. The Majano anemone is very invasive and can
quickly take over an entire reef tank.

So, after consultation with Greg Schiemer, I purchased a
4-inch Chaetodon ulietensis. Here are some links to this
butterfly fish:

You will also find a description of this butterfly fish in
Scott Michael’s excellent book, Angelfishes &
Butterflyfishes
. Reef Fishes Series Book 3, published by
Microcosm.

It wasn’t in the tank for more than a day before it went right
after these dreaded anemones. Of course, I’m very concerned with
what it will attack next. However, much to my surprise, it eats
flake food, and hasn’t shown any interest in any other sessile
animal. A word of caution, the behavior of any individual fish is
unpredictable, and furthermore, what it might decide to dine on
in the future is unknown. I will, of course, continue to report
on this individual’s behavior. Currently, it is doing the job it
was put into my reef to do.

I want to add that I purchased the fish by mail order from
Foster& Smith, and that it arrived well packed and in a very
healthy condition. They were the only ones at the time of order
that had this species in stock.
