Snow white eyes/HELP HELP

[freebyrds6]

:help: Okay I got up this morning and found that my V-tail Gruoper and Blue jawed trigger was dead. My puffer fish eyes are snow white and my lion fishes eyes have some white cloudy in them. It also appears that they have a small amount of slime on the bodies. My water CK out okay. I have done a water change. I do not know what else I should do. I also have to eles in the tnks that seem to be just fine.

Please give us some more information. What are your exact water readings for ammonia, nitrite, nitrate, ph, kh, sg, and temp. Have these fish been eating? How long have you had them all? What sized tank and how old is the system?
