HELP! SICK FISH!?! Whats wrong with them?

I have 2 silver Dollars, and I noticed on one of them that both of the eyes look like it hassomething fuzzy over them. Not sure what it is but I need help! Does anyone know? I will try and get a pic up later. Also I had about a 6 in Loach with an inch thick and he just died. He has what looks to me like cobwebs on him. Atleast that is what I would compare it to!
I used to have over 20 gubbies/endlers all of them died with/in 3 days of each other. Does anyone know what is going on with my tank?
Now the elgea Eater is dying too.... I have nothing to upload pics with, and I dont know any of the water info! I guess Im going up the river with no paddle!

 

Sorry to hear, cool fish.

I do not know of anything that just clouds the eys or looks like spiderwebs.
Please post pic ifyou can. How about more details? What are your water params ? Have you changed anything recently ? When was your last water change ? Do you have any real plants in the tank ?

 

Cloudy eyes usually indicates the fish is under some type of stress, test that water!!
