Repeated Fin Rot

[rdd1952]

I saw the 82 degrees but thought that was on the other tank as there are 2 different tanks, a 10 gallon and a 16 gallon, mentioned in the original post. The reference to the 82 degree tank only mentions the tetras, danio and platy as being in the tank.

Thank you, rdd. That is correct. Sorry for any confusion. The goldfish is alone in a 10 gal. unheated tank -- probably about 70 degrees as that is my room temp. I mentioned it, because I did once have it in that tank, but it responded well to med and fins have fully recovered. I use separate supplies for each tank, to avoid cross contamination. GF is fine.

I have used Mardel brand Maracyn powder, which is a 5 day treatment. I have never treated for longer than that.

Any feelings about water temp, adding salt, amount of water changes I am performing? I usually add 1/2 tsp. acquarium salt per gal. of new water.

Sounds like to me you wasnt treating for long enough, clearing the finrot up but coming back once off meds.
I would of done 10 days treatment.
Can't use salt if you have scaless fish, though corys can't tolerate abit of salt.

I know the site for betta but it still applies.

I personally like to continue treating with Fin Rot medications until I see good, solid fin regrowth (about 1/8"), even If that means I treat longer than the treatment schedule calls for. I do this because many times medications will stop the progression of the bacteria, but may not kill them all right away. If you stop treatment before all of the bacteria are killed off, odds are the Fin Rot will return as soon as you stop medication. Fin regrowth is an excellent sign that the bacteria have been taken care of

Is there any other fish in the tank with the goldfish.
As the first goldfish alone needs 20 gallon then 10 gallon for every other goldfish added to the tank.
Goldfish are massive waste producers and meed double the filter size to the tank.

Finrot and ulcers are bacterial, but ulcers can be caused by parasites like flukes.
Ulcers are a pink or red colour with a circling of dead white skin around the edges.

Med maracyn plus

The more meds you use the build a resistance up to them.
Are you cutting the meds to short, as in bad cases you can be treating fish up to 4 weeks.

I'll try "Maracyn Plus" ... I think that may have been the one that the Pet store guy had me use in the goldfish tank. I know it was a combination of more than one medicine.

Thank you for your descriptions. The platy that had a mouth problem began with a white spot near the corner of his mouth. Before long it was as if his whole bottom lip fell off. He died in the hospital tank. I treated the whole 16 gal. tank with Maracyn in fear that I had some dreaded killer living in there. No one else showed any signs of trouble for months later.

You can get columnaris spots which are a greyish white colour with a tinging of red sometimes around the spot.
Then there mouth fungus false name which is flexibactor columnaris, bleached out lip, fluffy mouth, or strands of cotton coming from the mouth, it can also rot the mouth and head away.

Very helpful. Thank you.
