[quote]Curing Fish of Marine Ich


There are several posts and threads in this Forum which describes the disease, choices for the cure, and the process to cure marine fishes of Marine Ich (Cryptocaryon irritans). It seems like a lot to read and it can get confusing. So here

Obviously the QT is the answer but how many of us really can say we QT every fish for the recommended time if at all?? That is the way of the world these days eh?? Instant gratification. I have been lucky enough not to have experianced MI(at least not visibly) but have had lots of experiance with fresh water ich which if I understand things correctly is not the same family of malady???

I agree, I've been playing the salt water version of russian roulette by not QTing new additions to my tank but I think its a wise statement to say "if at all possible QT everything." Its hard to get a new fish and not throw it in the main display but at the same time its risky business for sure. Not only could the new fish die from lack of any treatment but it could also contaminate every other fish. The more I think about it the more I want to have a little 10g QT tank setup.


None of my fish were introduced to the display without being quarantined. Especially the ones that are difficult to feed (like my S. marmoratus and C. rostratus). --- I feel like I will be shot in the head right now :unsure:

I know it's not easy to wait at least 6 weeks (IME and IMO), but as what Skipper said: "Not only could the new fish die from lack of any treatment but it could also contaminate every other fish."

When I get impatient, I read articles about MI and MV - and one of them that I have read over and over again is the article above. Just the thought of having an infected tank scares the hell out of me. I waited 6 months before adding my first fish - I would really hate that "wait" and the harmony that I have in my display right now be put in vain or destroyed by something I know I could have avoided.

why does everyone say "infected"? its infested isn't it? ich is neither viral or bacterial, I really liked the reference to the 11 month die off factor, lol if people just didn't buy fish

just thought i'd post about the hyposalinity method. i currently am fighting off ich and decieded on the hypo method. its actually pretty easy to apply. just got a ten gal tank complete tank at walmart for around $35. lowered the salinity from .24 down to .09-.08. all the white dots seemed to have disappeared from the fish. all i gotta do now is maintain for about 3 more weeks then bring the salt back up for a week or so then observe for about a week-2 weeks. so all in all i would say go with this method if u ever have to deal with this. which i wouldnt wish on anyoneeeeeeeeee

Thanks for mentioning the hyposalinity method, Tahoe69! ๐Ÿ™‚

Just wanted to add this one.

According to some experts, the most proven treatments against Marine Ich (Cryptocaryon irritans) are copper and hyposalinity. Although it seems not so popular yet, but accompanied with some success stories, the use of the anti-malaria drug in the form of Quinine or Chloroquine (a quinine derivative) has been tested by some aquatic professionals against the abovementioned ciliated protozoan parasite, as well as Amyloodenium, Brooklynella and Uronema. This maybe available as Chloroquine phosphate, Chloroquine diphosphate, Quinine Sulphate, Quinacrine Hydrochloride and/or Quinine Hydrochloride. Some experts recommend using Quinine along with hyposalinity to intensify and improve the results of therapy.

As quinine can blend well with water and does not dissipate, it is known to be absorbed by the fish and through the blood, the parasites are affected and expelled. It only has known effects on protozoans inside the fish and thus free swimming theronts present in the environment may reattach.

After the treatment duration, water change must be performed and an activated carbon must be used to absorb the remaining traces of Quinine.

There are a couple of disadvantages with Quinine. First, you can

Excellent post!! I'm going to make this a sticky, lots of good info about marine ich!

I have some malaria meds i never used. I was supposed to go to Haiti, but trip got cancelled indefinitely.
