what is the grey cocoon that incases a dead fish, if it does not get eaten by others in the tank...

I assume I'm not the only one, who has lost a fish, that crawled into a tight spot to die, and didn't get found right away, and if you don't have a large population of pest snails, or other inhabitants that actively eat dead fish, you find it a week later, incased in a grey cocoon... I'm assuming that is a bacteria??? which doesn't seem to effect live fish, or cloud your water... it seems to be part of a naturally cycled aquarium, as part of the "clean up crew" thoughts???

if I see one, I net it out to the trash, butI'm sure there are lots of smaller fish, that never get found...
 
My oldest male Sawbwa which died recently, had its rib cage exposed and part of its tail gone by the time I saw it (3 hours after I saw it alive). Amano shrimp don't wait around :blink: I don't think it's possible in a tank with amanos for a fish to become a cocoon of fungus.
 
For me, by the time I see a funky fungus or bacteria fish body the tank often stinks of dead fish smell. I don't have shrimp, but some fish snack on dead 1s...often with no stink. I try to remove dead animals but they can be hard to find sometimes.

Plecos are so good at eating dead fish that you don't even know that they're gone until you are looking for the dead fish. Even then you're not going to find the body the fish is just going to be missing and you're going to assume that it's dead and eaten.
