Since this board has been up, we have found there are several questions that routinely get asked in order to help diagnose problems. If you can have that information to begin with in your post, we'll be able to help right away (if we can!) without having to wait for you to post the info we need.

1) Your water parameters - pH, Ammonia, Nitrite, Nitrates and salinity (if appropriate). This is by far the most important information you can provide! Do not answer this with "Fine" "Perfect" "ok", that tells us nothing. We need hard numbers.

2) Tank size and a list of ALL inhabitants. Include algae eaters, plecos, everything. We need to know what you have and how big the tank is.

3) Feeding, water change schedule and a list of all products you are using or have added to the tank (examples: Cycle, Amquel, salt, etc)

4) What changes you've made in the tank in the last week or so. Sometimes its the little things that make all the difference.

5) How long the aquarium has been set up, and how did you cycle it? If you don't know what cycling is read this: Fishless Cycling Article and familiarize yourself with all the information. Yes. All of it.

We want to help, and providing this information will go a LONG way to getting a diagnosis and hopeful cure that much faster.

While you wait for assistance:
One of the easiest and best ways to help your fish feel better is clean water! If you are already on a regular water change schedule (50% weekly is recommended) a good step to making your fish more comfortable while waiting for diagnosis/suggestions is to do a large water change immediately. Feel free to repeat daily or as often as you can, clean water is always a good thing! Use of Amquel or Prime as a dechlor may help with any ammonia or nitrite issues, and is highly recommended.

Note - if you do not normally do large water changes, doing a sudden, large water change could shock your fish by suddenly changing their established water chemistry. Clean water is still your first goal, so in this case, do several smaller (10%) water changes over the next day or two before starting any large ones.

Can you get Mycobacterium marinum in freshwater?

Post by PuffTheMagicFishy »

Can you get Mycobacterium marinum (Fish TB) in freshwater? All the articles I've read seem to mention marine tanks only. Anyhoo, the reason I ask is that I have this very small scratch on my finger that I forgot about while cleaning the tanks last week, and so it got exposed to the water. Yesterday it started swelling up and today it looks like it has a dried pea stuffed under it. I'm getting rather worried. I've put antibiotic ointment on it and we'll see what happens after a couple of days. It may just be a run-of-the-mill infection.

I don't know if that particular bacterium survives in freshwater, but if your hand is swelling up that much that fast, I would definitely visit the doctor. Especially if your veins are beginning to show up around the area. Such infections can become very serious very quickly.

I believe you can, but I'd be more inclined to not panic and assume its probably a run of the mill infected cut, however if it does not get better in a day or two I'd definately be getting a doctor appointment and letting them know the situation.

But I'm one of those "farm girls" that if I get an infected cut I just lance it, clean it out, rinse it out with alcohol and keep going...

I recently read an article in Practical Fishkeeping about this where a woman became infected with Fish TB and while it is rare, it wouldnt hurt to get yourself checked out by a doctor. Best to be on the safe side.

Yes, fish TB can and does occur in FW.

See your physician. The odds are against TB, but it is a difficult infection to treat if it happens to be the case, so better to get it on record and checked out ASAP.

Thank you everyone for the advice. I think the swelling may have gone down a tiny bit today, so I'll still give it a couple more days with the antibiotic ointment. If it's still swollen on Thursday or Friday, or if it keeps getting bigger, I'll definitely go in to see a doctor. Normally I don't worry too much about infected cuts (they're just a nuisance), but I've never had one swell up this much. I'll let you guys know how it goes.[/i]

Mycobacterium marinum causes a chronic progressive fish disease found in freshwater, saltwater, and brackish environments.

Yep! That's the article that got me worried in the first place. :wink:

I tried lancing it yesterday and again today. Absolutely nothing came out, no matter how many times I poked it with a pin. Other than that, there has been no change in size and I am continuing with the ointment.

I would go see the doctor just in case. A petland worker here got it while cleaning the bioballs/overflow and it was pretty expensive for medications needed to treat it. She got scars from it as well.

The swelling has gone down to almost nothing, thank goodness! I'm going to go buy myself a pair of elbow-length rubber gloves so I don't have to go worrying about every swollen cut. Thank you everyone for your help and concern--thankfully it looks like a false alarm. :D
