Urgent, another corydoras flipping

Anonfish4

I was going to get sand tomorrow and I still plan to, but I noticed a dead corydora today in my tank. This is the same corydora who has been flipping the last few days. When I found him I can't tell if he was eaten or a parasite got a hold of him, but he was alive and well yesterday.

Does anyone know the cause? Should I get another corydora to fill his spot as now I only have two? I won't for a while if I do.

I honestly don't know what to do. My tank was normal and everything was fine, and now it's not.
Previously I had posted about how a fish was flipping and pacing the tank and had shorter barbells. Now that fish is dead.
Then a fish had a red mark on it's side.
The fish who has the red mark (less red, now white) is pacing the tank is flipping. I don't know what to do. My parameters are normal and everything. All I can think of is either the gravel (I'm replacing it with sand tomorrow) or a plant that I had added recently. I washed off the plant before I added it. It was an old plant that I used in another aquarium years ago but I thought would be fine. I feel like everything bad happened after I added the plant but it might've just been a coincidence. I've removed the plant as I don't want it in there anymore if it is causing problems.
Please help. I don't know what to do and I hate to think my fish are suffering right now.

Hi welcome to FishLore
I'm really sorry about your fish :( Honestly, those fish look like they have been dead for a while.

I doubt an old fake plant could have a parasite living on it that would do that to a fish.
Where was it stored?
I don't blame you for removing it. Sounds like a coincidence but it would make be paranoid as well.

Your other threads have some good info. Probably best to follow through with the advise there plus water changes.

Good luck!
