columnaris

G'day all, I seem to be having a unlucky streak these past few days. Today I noticed one of my neon tetras in my 15 gallon planted tank was hanging out by himself and on a closer look I saw it has a small white growth on its mouth, kind of making it look like it has a flat nose. A quick google...

This is my Scarlet Badis. A few days ago, I noticed this on her tail and I'm not sure what it is. Shes in a 3 gallon tank with 6 neocardinia shrimp and I have a sponge filter going. She's acting completely normal and feeding/hunting well. I was told it was columnaris, but I would have expected...

Hey guys/girls, So my male scarlet badis has had this growth on his lip, but its recently become quite large and stayed this way for the last 1.5 months or so (see attached pics). The closest thing I could find in the fish diagnosis guide is columnaris or mouth fungus, but it doesn't look quite...

I took a gamble, ordered some fish online, and put them right into my main tank (20H, should've QT'ed). They were apparently healthy last Thursday when they arrived, but over the weekend I started losing fish. The victims have white around their mouths, get sluggish, and stop eating. They die...

Hi everyone, I recently added some new guppies to my tank without quarantine ( lesson learned), and I guess they were infected with columnaris. The disease seems to be spreading quite fast to my other guppies and neon tetras. I have a dirted planted 55 gallon tank with several other fishes...

I have a Sterbai Corydora that has a growth on both pectoral fins. It looks brownish-white and blends into the fin color. Anybody know what this is a symptom of? I brought some new fish home and ended up contaminating my tank. I have been treating the main tank using Ich Attack. After...

I brought four platies home from the pet store yesterday and put them in my quarantine tank (5.5 gallons with a mature sponge filter and some loose plants). They appeared fine and were active and lively, but I noticed today one of them has slowed down and has some white, fuzzy-looking growth...

Bought some cories and CPD from the petstore this weekend. Long story short, 5 of the 6 CPDs have died (clamped fins, weakening, white dust/fuzz on back and sides, then dead the next day) and the survivor does not look well. Leaning towards columnaris. :help: The cories, weirdly, seem to be...

Hey so I have a Geo tapajos that has open sores on its head with white fuzz coming out. The root cause I'm sure is that I was a lazy/foolish aquarist and was overfeeding without increasing the frequency of my wc's and of course that's when fish get sick. I quarantined him in a ten gallon I had...

Hi everyone, I have a 30g planted tank. I have four male guppies, 6 neon tetras, 6 otos, and three male platys. When I got home from work yesterday I noticed that one of my guppies was lethargic and resting near the top of the tank. This morning I realized he had some bit of fuzz that reminded...

Hi everyone, I have a sick juvenile salmon red rainbowfish in a 600L planted tank with lots of driftwood and good hiding spots! I just tried for ages with a large and small net but no luck, she hides at the back of the driftwood. Can't catch her when feeding, she's too fast. Any ideas? She...

Question: Would you euthanize a seemingly healthy fish if it came from a badly diseased tank? Context: For the past 3 months I've been battling a very stubborn strain of Columnaris in one of my tanks and failed miserably all three times. I have lost 15 guppies/endlers, a betta, 2 tetras and 6...

I'm not sure what to do with my fish because I'm not exactly sure what they had. I was treating them with Microbe-lift Herbatan and took the carbon out when I originally thought it was ich, but then my fish started to pile up on top of each other on the bottom in the corner of the tank. Their...

I've been setting up a planted 20g long, have had my four corydoras for at least three weeks. Today i noticed that one of the corys has a hairlike, moldy growth over his mouth. He is also lethargic, and surfaces for air much more frequently than any other fish in the tank...

I may be on the verge of a catastrophe, and need help! I have already euthanized three cardinal tetras :( and my German Blue Ram seems to have it now! Description: It starts out as kind of a swelling of certain areas, like my ram has a swollen eye and mouth. It is white, not ich-like spots...
