Ich treatment killed all Rummy Nose Tetra

[Cutty]

Hello, can anyone explain why the following occurred.

I purchased white spot remedy by Blue Planet.

I applied the correct dosage for tetras and small fish.

Then I added black neons, cardinals, neon tetras, guppies and rummy nose tetras.

Within 10 minutes all of my rummy nose tetra were dead.

Does anyone know why this occurred?

Are they not able to be treated with white spot meds?

All tetras are sensitive to medication. Rummynose are a little more so. In the future, the safest treatment for ich is raising the temperature to 86° farenheit for 2 weeks.

I agree with @JuiceBox52 raising the temp to 86 degrees is best. Sorry about your fish, rummynose tetra are very sensitive.

Did the fish have white spot?
Why did you add medication, then add the fish?

If fish die within a few minutes of being treated with chemicals, then you overdosed and poisoned them. The best thing to do then is a partial water change to dilute the chemicals.

Yes, they did.

Not possible. I followed the instructions to the dot.

Even put in a bit less than what they prescribed for tetras.

Besides, that Wouldn’t explain why it only killed the rummy nose.

All the research I have read states raising the temp to 86 only speeds up the rate of the ich cycle. It doesn’t remove ich. The only way to kill ich by increasing the temperature would be to a temperature that would kill the fish long before the ich.

The white spot parasite is in its free swimming stage, it dies at 30C (86F). On rare occasions a heat resistant strain can develop and then you increase the temp to 32C or use copper.

-----------------
If you didn't overdose the rummynose, then the only other reason they died was if the tank water was different to the water they had been living in, or the fish had only just been purchased and they suffered from transport stress.

Cutty, you didn't answer Colin's important questions in his post #4.

All characins are highly sensitive to all chemicals. Rummynose are especially so. I am rather surprised your cardinals lived through this, though they may still have been seriously impacted internally and we have no way to assess this but the use of any of these "treatment" chemicals/medications will impact fish. And as others noteed, heat does kill ich and it should be the only treatment, if you see spots for ich.

Noted, thanks. Definitely won’t be using any kind of medications in the future.

thanks all.
