Imaginarium Ich Treatment killed my fish!!

I have 29g and I noticed ONE of the fish had several spots. I couldn't see any the day before, which is weird. I know it's ich 100% so I went out and bought imaginarium ich treatment. I dosed it accordingly & so far I've lost two angelfish, one hatchet fish(super old), & a platy. These fish in the tank weren't even showing signs of ich & were 100% healthy. I still have a few fish & there and I'm not even sure if I should keep treating. This tank has been cycled & running for a VERY long time btw so the only thing that I can think of killing them is the treatment. I bought Ich-X online but it hasn't arrived yet & the ich on my one fish looked super bad so I started treating with the imaginarium. How should I switch them over to the Ich-X? I've already done water changes because 4 of my fish passed away, but I re-dosed & waited a day after that.

 

Oh no! That’s incredibly strange! I’m so sorry for your loss!!

 

All the traditional ich treatments are harmful to fish and ich. You just hope the ich dies first.

There was a study on ich treatments and it was very common for treatments to kill healthy fish or to be just as deadly as ich.

By the time you see white spots on your fish, your tank has been infested for some time. The white spots are the only visible symptom of ich. When ich infests your tank tank the parasite is invisible. Just because you don't see white spots on all the fish does not mean they're 100% healthy. Ich tends to attack the gills first, which you also can't see.

It's not weird that ich seemingly appears overnight. The parasites have been multiplying and attaching to fish for several days. The white spots are not the actual parasite, but the fish's reaction to the parasite, which has been attached for some time. Once you see white spots on any of the fish, all your fish are infected.

I haven't had experience with Imaginarium ich treatment specifically, but any ich treatment will cause stress on your already compromised fish. That includes the heat method, salt method, or medication method. That's why it's recommended to avoid combining methods, like heat and medication, etc.

The active ingredients in the medications will be shown on the bottle. I'd compare between Imaginarium and Ich-X. If it's the same active ingredients, I don't know how changing brands would help.

 

Just use the heat treatment.
Turn the temperature to 86 degrees slowly.
Keep it there for at least two full weeks.
During the two weeks, you will do water changes, and vacuum your substrate to pick up any cysts that fall off. Do this every other day.
Hopefully at the end of the two weeks, the Ich should be gone.
Slowly return back to its original temperature. Then do another water change.
The higher temperature will speed up the life cycle of Ich.
