In light of the recent posts, and all the misinformation on the web and floating around in this forum, let me set a few records straight.

Mycos is nothing to be considered lightly. I have been in regular conversation with fish pathologists for almost a year now, and it is a very serious disease and in most of the fish available at your local pet shop. Their guess is 70% of the TRADE. That means ALL fish. You need to read the article I have created at the link below, and take it very serious, as it is based on the research of people that look at mycos for a living:

I have friends that have dealt or are dealing with this. FROM ONE FREAKING FISH I destroyed 3 years of work, over 500 bettas in one afternoon. I could not even enter my fish room for days. I dealt with fin rot, lesions, lifted gill plates, dropsy and the list goes on. I finally contacted a fish pathologist and sent THIRTY fish representing every tank or system I had. The ones with lesions tested positive for mycos right off the lesions they presented.

ALL were diced up and tested and ALL tested positive for mycos. Fish from 30 days to 9 months of age. It was recommended I send more fish to the leading researcher in mycobacteria here in the US to determine the strain. They were unable to grow the bacteria to determine what strain I was dealing with and was told that is not unusual for many mycos strains. It took DNA to determine what I had. My results and currently what many betta breeders are dealing with is M. Triplex. Thats right.. something you have NOT heard of. Google it. And you will find it shows up in people.

If you read the article I posted you will see there are different types of mycos. Some move fast and others a bit slower. But the end result is THERE IS NO CURE and THE FISH WILL DIE. Some mycos can be managed as there is no way to completely eradicate it. But you destroy the pathogenic ones and manage water conditions to reduce affect of the others.

I was told Lysol will kill it. Not knowing there were different Lysols I ran a major heavy solution through my barracks for TWO WEEKS. I drained that down, ran water through it a few days, drained it down and ran a super concentrated bleach solution through another TWO WEEKS. I brought the system back online and put some of my most promising fish in the barracks and EACH ONE CAME DOWN WITH THE DISEASE AGAIN! The ones still in the tank never got it. So DO NOT tell me you can bleach or use vinegar on this. DO NOT tell me it is not that serious.

So once again I have had to destroy some absolutely beautiful fish. More discussion with the pathologists and we found I did not use a proper cleaner. I sure as heck do now. EVERYTHING.., nets, hoses, tanks, lights water test vials.. EVERYTHING gets hit with the anti TB chemical after EVERY use. My trash cans for water are broken down and sprayed every few weeks. Even my hands between tanks. I set a timer as there has to be 5 minutes contact time. I refuse to destroy any more fish. I have clean stock now and I am going to keep it that way.

In the meantime. My recommendations.. for all it is worth..

Get a hold of a local vet or go online and get something that will kill TB. The article I linked to has a link to chemicals that will kill mycobacteria. Treat EVERYTHING in your fish room no matter how small. And treat any tank with it when you break it down... sick fish or not. Keep the stuff on hand and act like it is ever present to get a foothold in your fish room. Practice good bio-security and you should prevent it or get rid of it. If you have sick fish - destroy them, nuke everything and start fresh being more careful.

Yeah I agree. If it is mycobacteria it is best to cull. There's no 'giving them a chance' as there is no cure for it and it is inevitably fatal. Seen a few rainbowfish breeders run into issues with it and have to euthanise entire tanks full of fish, even the seemingly healthy ones.

It can also be transmitted to humans and cause potentially serious problems. That alone for me would be enough to make me not want to have any infected fish in my fish room.

This is very important information here from an experienced breeder.

Thank you Basement Bettas.

Hi. I have a fish with fin rot, a lifted gill plates. It's been like this for 2 weeks now and he's alive but seems to be BERY slowly recovering. Could this be myco? It came after I bred him

Basement Bettas 01-16-2013 08:57 PM

pictures please.. but this crap is going around. and as often as you buy and sell fish.. doubt you take any precautions.. good chance you have it. best to act like you do and take steps to get rid of it.

Basement Bettas 01-16-2013 08:58 PM

and who ever you bred him too has been exposed not to mention the fry will have it if the parents do. or at least a huge chance of having it. Go read those articles...

Mo 01-16-2013 09:05 PM

Okay. Not sure what it is as both o the females I've bred him to and the fry are okay. I really havnt taken precautions TBH I just havnt shared any water, no net sharing. Nothing that has come in contact with him has come in contact with others since I noticed the symptoms.. I'll get a pic soon. Could it be a less contagious and less harmful strain of Myco?

no such thing.. there are some that can be managed.. but they do not present like you are saying. Keep him separate and get a disinfectant that kills mycos. And use it. If you don't have it .. it will KEEP you from getting it. Lot of people dealing with this.. and just look at some of the recent .. my fish is sick.. photos. Mycos. Best to err on the side of caution..

Mo 01-16-2013 09:15 PM

Thank you. I will PM pics of this fish now. So does Myco usually last that long?

Sakura8 01-16-2013 09:23 PM

This is very important information that needs to be circulated BUT there are a few caveats that I want to add.

First, the majority of people on the forum don't have fish rooms or extensive (and expensive) breeding operations. For these people, the risk of contagion between fish is obviously minimal, especially if they have just the one fish.

Secondly, without the same necropsy/autopsy tests and tissue samples, it is impossible to know what a sick fish at a pet store may have. Saying that is has mycobacterium without these tests is irresponsible.* Many people have purchased sick fish and successfully nursed them back to health, myself included. I think a lot of people would agree that many of the sick fish at a pet store are suffering from poor water conditions, not myco. Therefore, I won't condone discouraging people from buying sick fish if they want to attempt to nurse them back to health. The people who do this do so knowing full-well the fish is sick and knowing full-well it may die. The vast majority of people are not ignorantly buying sick fish. As long as people practice sanitary fishkeeping and avoid contamination, go for it.

Thirdly, this needs to be made clear: mycobacteria is the same bacteria that causes fish tuberculosis. HOWEVER, just because a fish is diagnosed with mycobacteria doesn't mean the fish has fish TB. The fish we have seen on the forum who have been affected do not exhibit the same symptoms as TB.

Now that I've said that, again I want to say the information included is informative and well-put.

* Strictly speaking, yes, every fish has some small amount of mycobacterium, just as every fish has some small amount of every bacteria present. What I'm referring to is a potentially lethal outbreak of myco.
