I get a bit of stuff that gets put into my tank after cleaning my canister though its neglectible and has never harmed any of myc fish.
Like has been stated above, i would say it has been caused from killing the bacteria.
Hope its all sorted soon.
Hope your getting good help mate.
Asked where you were located becasue i know lots of fish people and shop owners around my area (NSW) who might be able to help you out with selling fish etc.
Your a smart person to seek this help, lots of people dont and find out the hard/expensive way about...
Sadly, yes, you are hugely overstocked. A tank your size is barely suitable for a pair of oscars alone.
You will certainly have to have a big think about what you like the most and advertise to sell or try and return the shop you got them from.

I have around 50 RCS.
Some days there out and about all over the place eating and looking around, then the next its hard to find 10 of the little guys.
Shrimp are great hiders, i wouldnt worry too much about them.

I have not lost any at all, even the smallest newly hatched cherrys are ignored or maybe inspected but left alone by all the fish.
I lost 1 cherry ever when my...
It hasent been said yet but your ehavily overstocked already by the looks of things assuming your tank is just as wide as the pic is.
