blood in eye?

[Shane Tesser]

Ok, have a strange one here, i have a very large black moore gold fish, he has the typical bubble type eyes. The past couple of days ive noticed that one of the eye sacks has red in it...i think its blood. Im guessing that he may have bumped it or...It has not grown any bigger, or got any worse, and i cant find any info on such a disease in g-fish. Has anyone had this before, should i be concerned? Other than the redness everything else seems okay.
