I noticed a few days ago our blue betta had a white discoloration on his back in the form of a circle.

Now the circle has widened... so it seems to be getting worse.

Can anyone help diagnose this so I know how to treat it?

Thanks,
Glenn

Nobody has any information? The white spot is larger today and darker white.

I guess I'm going to have to try an anti-fungal if I don't get any advice from this forum.

Hi there,

Sorry no one replied...we try to be fast...in fact, I'm not sure how any one missed it...oh well.

Can you give us a few stats on your tank? Size, temp, water change schedule, etc? If it's on his back in a circle shape, like a saddle, it may be columnaris, which is quite deadly.

Here is our columnaris treatment sheet, written by an incredibly well informed betta expert...

Sorry, I just wasn't around last night. My first guess is columnaris ("saddle back disease") as well. I couldn't find any betta photos with columnaris (I know they're out there!) but here are some other fish with the disease:





As you can see it's sort of a white discoloration right on top of the fish, usually around the dorsal fin. There are many, many causes of color loss and discoloration in bettas, but columnaris is one of the more common.

The information that Betta_Girl asked for is useful in helping us diagnose your fish. Also, pictures would allow us to give a more definite diagnosis.

Thanks for the replies.

That looks like it, although it isn't that big... yet... and it's slightly closer to the head but not much.

He's in a 2.5 gallon Mini Bow tank with a 25 w heater that keeps the temp between 78-80. It's also got a whisper filter that has it's suction reduced.

We do a 100% water change every 7 days.

I just read that link above... it says water at 74 degrees.... should I go that route? I always thought that was too cold.

Thanks for you help.

Here's the best I could do picture wise... you can see the white blotch on his back. The 3rd pic is to show the tank:

Cute tank, lucky fish. smile1.gif

To me that does look like columaris. It is hard to tell, but it looks kinda raised and such. Use (any one of these) Triple Sulfa, Tetracycline, Furan-2, and Erythromycin. Adding a half teaspoon of aq. salt per gallon and putting the temp at 74 will also help.

I took a ton of pics, very hard to get good ones.

The mark does not look raised to me... it simply changed the color of the skin.

This tank is in my 2.5 year old daughters room. His name is "Mel".

I guess I should do an immediate water change? Should I throw the stones out and replace with new? Anything recommended to clean a tank with to ensure an fungus is removed?

I would do a 100% water change before beginning treatment. If you do a full treatment with medication you should not have to throw any rocks or decorations away...the meds take care of that as well.

But act soon - if it is columnaris, it is a fast killer when it gets going.

Yes, you should put the temp down to 74 -- and yes, you're right, that's too cold for a betta normally! Keep the temp there just for the treatment. This is because columnaris thrives in warmer water, so it will speed up and be harder to kill at temperatures higher than that. At temperatures lower than that, though, your betta's immune system probably won't be able to help it, and the medication doesn't work as well. So 74 is ideal. After your fish gets better, get the temp back up. smile1.gif

Be sure to use the aquarium salt as well as the medication, and be aggressive in treating it.

I agree, your tank is adorable! That's a wonderful betta home. smile1.gif
