really big eyes - what is wrong?

[new2ovas]

well I have a 90 gal mixed african tank with one Demo, yellow labs, and a few other ones.  I have now lost two yellow labs in the last six weeks or so.  I didn't notice anything weird with the first one but the second one I noticed had really large eyes for about two weeks.  I also have a few of my other fish that seem to have the same thing.  They almost remind me of a character from starwars or something.  Anyways I was just wondering if anyone knows if this is normal and what is it.  As well if it is not normal why is it happening and what can I do.

TKS again,

cheers

Google for "pop eye fish", that might be it.

Also make sure your water is happy.
Ammonia 0 Nitrite 0, keeping nitrAte in check, GH that africans prefer, and constant PH and temp that africans prefer.

Any cloudiness inside the lens?  Anything else look/seem wrong or off?

Definitely read up on popeye. Its not normal.
