This is a re-post of what I wrote in ReefCentral on 3/09/2013
Many anemone keepers know, the collection and shipping process from ocean to local fish store (LFS) is a stressful event. Most host anemones do not survive this process without help, especially H. magnifica and S. gigantea. Other host anemones also have high mortality. Most succumb to infection in the first 4 weeks on arrival to LFS. With help from other anemone keepers at ReefCentral.com Anemones and Clownfish Forum, I have come up with an antibiotic protocol that seems to be successful and drastically improve the initial survival of anemones during this critical time.
The antibiotic choice: Ciprofloxacin (Cipro), a floroquinone antibiotic or Trimethoprim/sulfamethoxazole (Septra) combination antibiotic
There are several reasons I choose these antibiotics. They are broad spectrum antibiotics that should, hopefully, cover most pathogens involved. These antibiotics covered most of the pathogens involved in a saltwater wound infection in humans. This is not to say that pathogen that infected the anemones are the same ones that infected human. However, we have to start somewhere and these two antibiotic are reasonable choices. The other reason for choosing these antibiotic is that they are inexpensive and widely available. Cipro and Septra dissolve well in water and will break down with light exposure in a tank environment. Another antibiotic that can be use is levofloxacin (Levaquin). However, Levaquin is a newer fluroquinone and much more expensive because generic are not available.
Instruction:
The dosage for continuous exposure (not dipping) in a hospital tank is Cipro 250 mg or Septra 160/800 mg per every 10 gal of water. I recommended that anemone be treated in hospital tank. I used a standard 20 gallon (high) tank, power head (PH) , heater, egg crate and possibly an air stone. I also recommended that full light is provide for the anemone to help it recover via photosynthesis. The hospital tank is divide into two compartments by the egg crate. Place the anemone with an inert object (a mug or a medium piece of rock) for it to attach to in one compartment. In the other compartment place the heater, PH and +/-air stone.
Fill the hospital tank half way (10 gal) and added either Septra or Cipro, then added the sick anemone. The hospital tank water needs to be keep stable with respect to temperature and salinity. I recommend that all the water in hospital tank be change daily as the day-time cycle comes to an end. After a water change add antibiotic. The best method to add antibiotic into the hospital tank is to rub the tablet between thumb and index finger in front of the PH until fully dissolved. With reasonable light, it is likely that all or most of the antibiotic will be degraded by the end of the day-time cycle. Adding medication at the begin of the night-time cycle, should give optimal antibiotic exposure for the anemone for most of the 24 hour time period. Adequate circulation, with small PH, is a must. The hospital tank will have a minimal ability to process ammonia, therefore feeding sick anemone is not recommended during treatment process. I do not recommend tapering the dosage of the antibiotic because low level antibiotic treatment is what causes problems and creates resistant strains of bacteria.
Anemones often discharge various substance when they are not well. When the hospital tank water have solid discharge, I recommend removal of these discharge. At any time, if the water of the hospital tank is cloudy, I recommend a 100% water change and new antibiotic added.
Length of treatment:
It is recommended that the anemone is treated for a minimum of 7 days, and at least 3 days after it stops deflating. Early termination of treatment is a mistake that has caused me to loose a few anemones.
Disposal of antibiotic containing water:
There is no special treatment needed for disposing water containing antibiotics. Cipro and Septra will break down quickly with light exposure and will not stay around long in the environment. Short course of antibiotic use like in this protocol should not have significant impact on the environment. It is harmful for the environment if there is a continuous low level antibiotic discharge, but not for short courses like in this protocol . In human usage, these two antibiotics are eliminated unchanged by the kidney, and flushed down the toilet into the sewage system, which is what we are doing with our treatment water. It is unclear if treatment by bleach will do anything to the antibiotic. If you are concerned, store the water and put it under sunlight for a few days then discard.
I clean the hospital tank and all equipment thoroughly include bleaching the full set up in fresh water. Once thoroughly cleaned, the hospital tank can be dry and put into storage until needed.
