Well, I examined my fish and notice 1 or 2 of the symtoms. The gills are a bit swollen. I don't know about the mouth, though. The guy didn't really give a front side picture.
Just to be sure we are on the same page, is this the link you were reffering to
Guppy Designer - Flexibacter columnaris? I couldn't get your link to work (I think maybe because it had the word "
Guppy" in it and tried to send me to the fish profiles). I just googled "
Guppy designer - Flexibacter Columnaris". And clicked on the first thing that came up (guppydesigner.com).
Anyway, there were a series of sentences that would make me think that my fish don't have this diesase, such as;
"They also found significant differences in the strains. They range in the symptoms they produce and their virulence. The most virulent strain can kill a tank overnight. Another strain may take a week to ravage a tank. Although the researchers found four strains, it is possible there are more."
(maybe I discovered a new strain
) (just kidding)
"The most effective treatment occurs when the
Guppy first shows signs of the disease and before it stops eating. If the
Guppy has had it for three days, it is extremely difficult to cure."
Oops! That leaves my fish out! (maybe that only applies to guppies)
There are a few more contridictions but I will not go into them.
I've noticed that after I added an airstone (couple days ago)(you might have seen the thread "am I driving my fish crazy!?") the diesase almost seemed to mutate. The symtoms that had lasted over 2 months had changed in a couple days. Maybe it is worsening. I don't know.
I would have to say, it appears my
Swordtail has it the worst (he is a glutten!). The symtoms of this unknown diesase that he has is;
1. Blackish brown lining around his mouth (it appears to be rotting
)
2. Somewhat swollen gills (what my female
Swordtail had before she died)
3. Darker, almost black coloring around the mouth
4. Increased agression (this might just be because the female died recently)
As far as I can tell, he is my most active out of 9 fish (5 in his tank including him), even the cichlids. He eats like a pig on caffene. If you don't look closely at him, you wouldn't know he is sick. The female
Swordtail died from (appearently) the same diesase. Her symtoms included;
1. Major fungus/bacteria/parasites at the mouth (probably bacteria but I don't know)
2. Swollen gills
3. No activity (sat at the bottom at gravel in awkward posistions and only moved every 5 or 10 minutes)
4. Looked "depressed" (call me weird but sometimes I think I can tell my fish's mood by staring in its eyes, I think fish have more facial features than we give them credit for)
5. White coloration on the gills (my male
Swordtail is starting to get this white coloration)
I think salt is a good idea for pretty much any diesase (excluding a few). I read somewhere that catfish couldn't handle salt (I have an albino (bronze) corydoras (cory cat)). Has anyone ever heard this? Or had good/bad expiriences with cories and salt?
brief outline;
don't think it is that
Guppy diesase someone reffered to

Swordtail might be taking a turn for the worst

Sorry for such a long post. It is pretty bad when you have to spend an hour in a half writing a post
.
Thanks for the help!
Unbeatable mouthrot?
