After further research and a couple forum posts at, I’ve come to the unfortunate conclusion that parasites are the cause of the cloud eye in one of my blue diamonds.

Being internal, the parasites are more aptly handled with medicated food instead of water treatment. This proves insanely difficult since my discus snub basically everything that doesn’t rhyme with ‘bloodworm’… including the medicated food.

I was intending on feeding them a mix until they start eating the medicated stuff, but that’s obviously not going to work. I’ve decided to skip feeding for a day and then only offer them the medicine. If that fails too, I may have to look into alternative methods of treatment. I’ve read a few articles in which people have created their own medicated food using beef hearts. Apparently, beef heart is nearly irresistible to the discus.

A few people have indicated I wouldn’t have this issue had I ordered my discus from a breeder. I disagree. Though I’ve never ordered from a breeder, I prefer to see the fish and their environment before I drop $50-$75. You wouldn’t buy a car from someone just because they claim it runs great would you? I certainly wouldn’t. To me, it’s the same principle… but I guess in reality, it’s all a matter of opinion.
