Fin Rot Treatment Caused Burns?

[Novice betta owner!]

Hi All,

i have numerous problems with my Betta, just recently he has had fin rot i used an interpet over the counter fin rot treatment (i live in the UK) and over the past week he has really perked up.

he has had a 30% water change today and further application of treatment and over the past 6 hours his tail has become bloodied and he is lethargic and resting at the top of the tank.

I have taken about a fith of the water away and replaced with conditioned water incase he has been overwhelmed by the treatment.

Any ideas?

I see you don't have a filter, and you didn't list your water parameters so I guess you can't test your water. Do a large water change as it sounds like there is a good possibility that the water has built up large amounts of ammonia or nitrItes since you cut back on the changes. You can always replace the medicine that you lose in the water change. Clean water is the best thing you can do for the fish now. I'd suggest daily partial changes if your tank doesn't have a filter. Also a heater if you don't have one. Most importantly get a testing kit to check your water. What type of dechlorinator do you use?

thankyou for your reply I have never used a filter but have recently purchased one unfortunately the treatment suggests to remove the filter whist dosing and just use an aireator (the treatment affects certain components of the filter).

The tank is heated and the reaction the betta had occured directly after a dosing of the treatment (as instructed) and partial water change, (we have had him for approximately 2 months and he has never suffered ammonia burns before, hence the belief it is due to the treatment.

we use tetra aqua safe conditioner, and do not have a parameter testing kit.

This am he is lethargic, refusing food and the red area is now darkened and the obvious areas of fin rot appear to of come away, so I am wondering if this is a normal reaction to the treatment except after the first dose (1 week prior) he did not react as badly (just slight lethargy no reddened patches).

thankyou again, he is a great little fish and was sold with very poor advice, most of my knowledge has been built up from forums such as here.

With a 5L tank, when you were changing 100% weekly, you were probably barely keeping the ammonia down enough to keep the fish from harm. Now with only 30% weekly, you will accumulate too much ammonia in the tank withing two weeks time. I really think you should do a 100% change since he is used to that and see how he looks then. Then perhaps medicate the fresh water if the fish looks up to it in a few hours.

It's ok that you don't have the filter in now as it wouldn't really do much anyway except the carbon might extract the meds. Once you install it, you'll still need to do large water changes regularly until the filter builds up a good supply of beneficial bacteria. Change the water, it's the best medicine.

Thankyou for your advice the 30% water change was as advised when we bought the treatment and the lethargy/bloodened fail tin happened within 6 hours of the 2nd application of treatment and a further 30% water change (a week since the 1st treatment).

I have done a 75% water change and added a little aquarium salt (as well as conditioner) he already seem more active, the rot has attacked approximately half the way down his tail but all other areas are almost untouched so I am unsure where to go from here, I had bought a filter ready to use for when he was back to his normal self but don't want to stress him further (he has an oxygen pump in for now).

If you are using interpet number 8 anti fungus and finrot, it says harmless to filters on the side of the box. Maybe it just said to remove carbon (black) media from the filter as that can remove medications?

If you have no tests to test your water and confirm ammonia and nitrIte are 0 then you can't say it's not the water quality causing the problem.
Since there was no filter in this tank, the fin rot and sickness itself is probably caused by bad water quality issues.
Also it may take up to a couple of months for a new filter to start doing it's job. When was it added to the tank?
And additionally, what type of fin rot treatment are you applying? There are treatments for fin rot caused by fungus and fin rot caused by bacteria. You may be using the wrong one.
Fin rot is initially caused by bacteria and if not cured the fish will eventually be attacked by fungus.
