Barb With Popeye And Something Else?

[1cherry3goldbarbs]

Hi. One of my barbs developed a bloody popped eye yesterday. It is not cloudy at all like most of the web pictures of popeye that I've seen. The area around the eye is blood red and inflammed. I've started treatment with Maracyn-Two, but I was wondering what would cause the eye to be bloody instead of cloudy. Thanks.
