Black-Eyed Guppies

[This Old Spouse]

I have a couple of young male guppies whose eyes are completely black. All the other guppies have eyes that have a lighter circle around the black pupil, but these guys have black all the way, kind of like a doll's button eyes. They're also acting a bit "off" by hanging around the bottom. I don't think they're injured. They're both about half grown.

Has anyone seen this before, and what should I do?

Yes and nothing you can do. I'm not sure what it is caused by, but I suspect that it may be a rogue gene.

i have never had any problems with fully black eyed guppies, they've always been just as healthy/active as the rest, i do get quite a few pop up now and then

Problem is, they weren't born this way. This is something that has developed with them!

And by the way, it's actually with the endler mutts. And this morning they seem back to normal, which is really confusing.

Weiredly enough I'm sat watching twilight and the vampires eyes change
Colour after they “feed”! Are they particulary fond of blood worm?
