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.

A week ago I noticed a fish flipping and glass surfing but from one side to another and had short barbells. Now that fish is dead. Another had a red (now white) mark on it's side but acted normal. Now it's flipping every now and then, but not as much. Only one fish isn't doing this.

Honestly, those fish look like they have been dead for a while.
