cool, that happened to me once, remember the spot you caught them cause now i cant find them back. in the wild they live on plant and the caroteen gives them the green and blue, in captivity they live on fish and fish food, so the blue comes out. Ive had hundreds of c fish and only have had one batch turn blue. congrats

isn't it very similar to albanism in vertabrates. As their blood is copper based isn't that a large part of what you are seeing hemolymph etc.

Thats pretty cool, hang on to them. I don't have any blue ones, just red and I feed them to puffers.
