Heteractis Magnifica Anemone - Care and Medication Question
Hello! And thank you for your time.
First, some background. My tank is a 210g with a 40g sump. It has been
running and healthy for just over 14 months. I myself have been in the
hobby for almost 4 years. In that time I have taken a strong liking to
anemones, and have had a great amount of success with them as a result
of learning from sites like yours. In my current setup I have many
corals, fish, and anemones that are all living peacefully due to careful
placement and purchasing.
<Okay! Am sure you know of the dangers of mixing Actinarians, and doing
so w/ other Cnidarian groups>
Five months ago I purchased a Magnifica anemone at a LFS. It did not
immediately take to my system due to a low alkalinity, but was recovered
and settled after about 2 weeks once I fixed that. About four months
ago, I added a second Magnifica from the same LFS. This one never had
any trouble, but for a few weeks fought with the old one for his spot
and finally won. The first one moved to a different spot and settled a
little higher, closer to the lights. Fast forward to 3 weeks ago. I sold
the first Magnifica to a fellow reefer, and it is doing well. I did this
to make room for a new Magnifica of a more preferred color, which I
purchased from a reputable online seller. My question is in regard to
this "third" magnifica.
For the first 2 weeks it did well, and ate every other day with no
About a week ago it suddenly spit out it's meal after dark on feeding
day, and ever since then it has deflated and inflated repeatedly in a
cycle of about every 8-12 hours.
<Mmm, doesn't like something here>
It does not appear to be timed to the light cycle at all. When it is
inflated, the mouth does not completely close, and when it deflates, it
has a badly gaped mouth.
<Also "bad signs">
I have heard some people suggest
that it may be trying to fight a bacterial infection. What are your
thoughts on my situation?
<Far more likely something, someone else in this system it doesn't
The first Magnifica is still well, as is the second one, which is in the
same tank, under the same light and flow as the new one. I have also
done 3 water changes this week, as well as change out
the carbon. All of my parameters are good (SG is 1.025, no PO4 or NO3,
<Mmm, photosynthates need some (measurable) phosphate and nitrate...
Alk is 11, pH is 8.0). I am considering transferring the sick anemone to
a QT and treating it,
<Just moving it will likely help>
but I would like to know what you can share regarding treating these
anemones. I have heard suggestions of using Tetracycline,
Doxycycline, and Cyprofloxacin, with Cipro supposedly showing the best
results, but no studies have been done that I know of. Any input would
<I don't suggest exposing this anemone to an anti-microbial. Not of much
probable value, and considerable potential downside. Bob Fenner>
