The Groumi's i think faught each other to the death the oldest still survives
the angel is the only other fish that looked ill. he had bug eyes, and was very sluggish and had no appetite

What are the symptoms? Any physical symptoms, are they still eating normally, pooing normally? Without some more information it is very hard to help.

thats just it most of the diseased have looked completely normal and healthy until they are dead. the only one that looked sick was the angel. it had mild pop-eye was very sluggish stayed in the bottom back corner almost always. the two groumi's i think got killed by the older groumi but i have not seen the groumi pick on any of the other fish since the two groumi died

The angelfish having pop eye is symptomatic of something else usually. Popeye is not really a disease in itself, it is usually brought on by other things such as water parameters. What kind of test kit are you using and how old is it?
Is there any white stringy poo in the tank? They were eating normally?
The gourami's quite well might have been attacked by the older gourami, gourami are quite territorial. Quite often you can't keep more than one in a tank together.
