Emergency dying fush

[cleanbuttpotatoe]

Hello,

i did my two week 20% water change yesterday and I wake up today to by royal gramma, my blue fish and q cleaner shrimp dead. I checked salinity and it’s at 1.024, ph at 8, ammonia 0, nitrite 0, nitrate 0-5. Temperature 79

i frankly don’t know what I did wrong but this breaks my heart as I’ve been taking care of this fish for over a year. I don’t know how I ****** up.

My two clownfish are struggling to breathe. Please help me to figure out what is wrong

So sorry for your losses.

Start by adding an air stone and pump to help over aerate the tank. If your outside air is good and you can reach it, I’d push outside air in just in case it is an indoor toxin.

Any chance air freshener, cleaning chemicals, etc used anywhere near the tank?

can you please post pictures and videos under white lights of your tank and remaining fish? That will help a lot.

I took a video. Here it is in white light and thank you

Video won’t play on my end (iphone) - could you try linking it as a YouTube video or just some white light pictures?
As mentioned, it seems likely that some contaminant entered the tank if they only started showing symptoms after the water change.
When’s the last time a new fish went in? Was it quarantined?
