Jo varmere vand jo hurtigere dør de.

Jeg er heldigvis ikke ekspert på emnet.

Det er ikke en bakterie men en encellet protozo -> en cilieret protozo. Hvid fiskedræber er ernæringsstadiet af Ichthyophthirius multifiliis. Men jeg forstår slet ikke din tanke med at flytte fisken for at udrydde parasitten. Parasitten borer sig jo ind fiskens hud så du flytter jo bare problemet...

Jeg har dog medicin parat hvis uheldet skulle være ude.
Den med saltkur vil jeg overlade til andre.

Jeg købte 1½ medicin til hvid fiskedræber i et koi-center i Roskilde for lige omkring 100 kr. og det virker fint på højde med faunamor... Jeg har til 3000 liter i den flaske... :O)

Afhænger vel også lidt af andre vandforhold blødt/hårdt osv.

Fiskedræber!
Ichthyophthirius multifilis is a very common protozoan parasite that finds the aquarium environment a most hospitable location for carrying out its life cycle. Because of the low densities of fish in large volumes of water in the wild, even though every cyst can release hundreds to a thousand or so swarmers, few if any will manage to find a suitable host. Those fish that do get infected will likely have only a single or very few parasites attached to its body, which will soon fall off. The fish will heal and be none the worse for it. In the wild, Ich is really no big deal.
A home aquarium, by contrast, is a confined space packed with many fish (relatively speaking). A single Ich parasite brought in on a new fish can quickly multiply and decimate an entire tank full of fish. Unlike in the wild, every larva has an excellent chance of finding a host, and each fish can end up with hundreds of parasites attached to its gills, fins and body. Such an onslaught is too much, and the fish dies from respiratory distress caused by gill damage, osmoregulatory imbalance caused by the many punctures in the fish?s skin, or secondary infections of bacteria or fungi that attack the open wounds.
Ich is also known as White Spot Disease. It is characterized by the presence of small white spots, like a sprinkling of salt, that may appear anywhere on the fish. The fish may dart about in the water, and flick or rub its body against the substrate or other objects in the tank. As the condition advances, the fish may become very slimy, clamp its fins, stop eating, and become very listless.
The standard chemical treatments are often effective, but they can be just as toxic to fish and plants as they are to Ich. Sometimes the medications are not effective. Many aquarists are interested in trying a more natural approach that doesn't subject their fish (or themselves) to potentially dangerous chemicals.
Ich Life Cycle
To better understand how it can be treated, a basic understanding of Ich is helpful:
1. Parasitic Stage - The first stage (trophozoite) is embedded in the skin of the fish, and feeds on fluids and tissue cells. The fish tries to protect itself by producing more cells around the trophozoite, which leads to the formation of the tiny white spots.
2. Intermediate Stage - Eventually the trophozoite morphs into a trophont, detaches from the host leaving an open wound, and swims freely until it locates a suitable place to settle.
3. Reproductive Stage - Once the trophont settles, it forms a sticky wall around itself and becomes a cyst (tomont). Inside, the tomont divides into many hundreds or even thousands of tomites.
4. Infectious Stage - The tomites are released into the water column and swim freely until they attach to a host, starting the cycle over again. If a tomite doesn't find a host within a short period of time, it will die.
The Ich life cycle is temperature dependent. Higher temperatures within its livable range speed up every stage of the life cycle, while the lower temperatures will slow it down. At 18°C/64°F the cycle takes 10-12 days to complete.
It has been found that Ich does not infect new fish at 29.4°C/85°F (Johnson, 1976), stops reproducing at 30°C/86°F (Dr. Nick St. Erne, DVM, pers. comm.), and dies at 32°C/89.5°F (Meyer, 1984), [1]
Treatment
Now that we know a little more about Ich, we can develop a safe and effective natural treatment plan to eradicate it. A multi-pronged treatment plan offers the most assurance of complete eradication of Ich and TLC for the fishes in your aquarium. As with any treatment, carefully observe the reaction of your fish to any changes you make in their environment. If an adverse reaction occurs, discontinue and try another approach.

Har før hørt om en "kur", der består i at man flytter fiskene fra det angrebne akvarie fra akvarie til akvarie over en periode på 10 dage - en flytning hver 12 timer, og der skal så lidt vand med, som muligt. På den måde når fiskene ikke at blive angrebet af nye cyster, og snylterne når at dø, inden fiskene kommer tilbage til samme akvarie igen. Der skal - afhængigt af temperaturen, bruges 10 akvarier til formålet - men det behøver jo ikke at være 720-liters ;-)

Hvad fiskene siger til at blive fanget med 12 timers mellemrum, skal jeg ikke kunne sige. Medicin er i hvertfald en risikofaktor for fiskene, idet det belaster deres organisme - ofte ligger behandlingsdoserne nær fiskenes forgiftningsgrænser.
